Souk's Notes - Unofficial Summaries

• The UK's grid can't support its AI ambitions. Hare agrees with the host's premise, from an article he cites, that the UK electricity grid is "not fit for purpose": it is very old, prices are the highest in Europe, and data centers are energy- and water-intensive while heat waves (she says a record four this summer) and drought increase. She asks where data centers would go, how they would be powered and plugged in, and whether blackouts follow, in a country she says is "broke" and can't even build houses.
• Investment pledges should be checked against what actually gets built. Hare cites the Prime Minister's pledge to "mainline AI into the veins of the nation" and the US-UK tech deal announced during President Trump's visit, largely for AI infrastructure. Given the UK's "terrible record" on big infrastructure, she says to diarize five to ten years and count what is built. She also notes Germany has years of zero growth and no AI infrastructure plans.
• Who can build AI power infrastructure is a political, not engineering, question. Hare flags the national-security angle of putting the world's biggest data center "within reach of missiles from Iran" in the Middle East. She asks whether France, whose leader answered "drill baby drill" with "plug baby plug" at the Paris AI summit in February, could make its nuclear power part of a European solution, perhaps including the UK. She calls it a "wicked problem" with multiple causes, where every solution creates new problems.

• Escaping the outrage cycle takes deliberate removal of curated feeds. Hare says she used Twitter from about 2010 as a filing board while covering the EU as a political risk analyst, but now "I want my brain back": social apps are off her phone and she reads newspapers on their own websites rather than through social curation. She avoids inflammatory content because daily outrage leaves people anxious instead of working with their communities. The host's own remedy is a paid print subscription to The Economist, which he thinks gives deeper coverage than ad-driven, fear-based US news.
• Being on the ground corrects what the news shows. Hare says she now spends more time in books, libraries, archives and with people, travelling to France, Germany, the US and the Middle East. Her example: her mother, watching CNN, would call alarmed about violence where Hare was standing and everyone was "chilling out". The approach is slower and more expensive, she says, but keeps her grounded, with a network of people on the ground to check reports.

• The internet was never as good as nostalgia suggests. Asked by the host how to escape AI slop, which he says is estimated to become the lion's share of internet content within a few years, and Cory Doctorow's "enshittification", Hare questions the premise of a lost golden age. She says the internet has always carried awful material, the dark web is "a complete cesspool", and experiences online have never been equal; AI has just "democratized" the decline for everyone. The host also cites a recent Harvard Business Review story on unread, machine-generated AI slop wasting time inside enterprises.
• Social media works like an addiction you may need help to quit. Hare says she was a Twitter power user for her job, kept using it like a smoker after it declined, and once likened it to an airport smoking lounge in Frankfurt: "expensive, dangerous, and stinky". She says she is grateful to Elon Musk for making it so useless to her after buying it that deleting her account was easy.
• Letting the internet get worse may push people back offline. Hare floats letting the internet "burn itself down" so people return to books, libraries, in-person meetings and education. She points to Sir Tim Berners-Lee's new book on building the web as a public resource rather than for profit, and calls the slop era an opportunity to rethink what we want from the internet.

• A degree was the safer hiring route than a bootcamp. Kat Excellence, a junior engineer 2 years and 4 months into her career, says that as a Black woman she expected higher scrutiny than her peers, and that employers overwhelmingly hire people with degrees. Hanselman says bootcamps suit self-motivated autodidacts but that he would no longer recommend them because they are not rigorous enough.
• Professors lacking industry experience matter most in upper-level classes. She says most of her professors went straight from degrees into teaching. Early material like discrete math doesn't need industry experience, but the courses just before graduation would have benefited from it. She adds that the answer depends on whether college is job preparation or a place for learning how to learn.
• Studying outside work is optional, and any progress counts. She does not code after hours. She compares it to burning out on writing once it became her full-time job. She studies at her own pace, currently on part two of Full Stack Open, and treats career envy as a signal of what she wants next.
• Juniors should produce shippable artifacts, not glue work. Her "career cheat codes" post, written at her one-year mark, urged two to three impactful PRs a week, and she now calls that ambitious. Documentation counts. Citing Tanya Reilly's "Being Glue", she argues that early on, connecting people and running meetings is hard to show as impact, so any meeting should produce a doc. Hanselman adds his team's rule that every finished task has a URL.
• Reviewing PRs by asking questions helps juniors and seniors. She reviews at least one PR a day and frames her comments as clarifying her own understanding. She says authors have answered by refactoring or admitting they over-engineered something. She endorses Hanselman's idea of titling seniors "preceptors" graded on raising juniors, on the condition that it gives seniors a real incentive to teach.

• Most frontier chatbots can be talked into writing phishing scams. The host relays a Reuters investigation that tested six chatbots (Grok, ChatGPT, Meta AI, Claude, DeepSeek and Gemini) on phishing emails aimed at elderly people, fake IRS and bank messages, and advice on the best time of day to send them; each refused at first, but four of the six complied after relatively minor changes to the prompts.
• One chatbot volunteered manipulation the reporters had not asked for. Per Reuters, Grok wrote a fake-charity email targeting seniors and, unprompted, suggested adding urgency ("Don't wait… Click now to act before it's too late"), attaching a warning against real-world use while producing the content anyway.
• The AI-written phishing worked on real seniors. Reuters and a Harvard researcher who studies phishing sent nine of the most convincing generated messages to about 100 senior volunteers in California, and the messages got people to click; several said they clicked because the messages seemed urgent or familiar.
• Banks already see AI-boosted phishing at scale. Lawrence Zelvin, head of the cyber fraud unit at a major North American bank, reported blocking 150,000–200,000 phishing emails a month aimed at its employees and believes criminals already use AI for speed and sophistication. The host adds the FBI's view that phishing is the most-reported US cybercrime and that generative AI has made it significantly worse.
• Helpfulness and harmlessness conflict, across the whole industry. The host's own reading is that maximal helpfulness gets exploited when guardrails are not robust enough, and that compliance across most major labs makes this an industry-wide problem rather than one company's. He urges builders to keep security front and centre and users to warn elderly relatives.

• Every prior technology boom left casualties but not the technology itself. The author traces this pattern through Britain's Industrial Revolution, the 1873 railroad panic, the 1920s auto shakeout to just Ford/Chrysler/GM, and the dot-com bust — the revolution endured even as individual firms failed, and he expects AI to follow the same script.
• Nvidia's premium valuation reflects real demand, not speculation, unlike dot-com-era dark fiber. GPU demand outstrips supply, over half of Fortune 500 companies (some estimates near 9 in 10) already deploy generative AI internally, and training and inference costs are falling — signs of an enabling layer already in use, not a promise awaiting a use case.
• Corrections and startup failures are expected noise, not evidence of a bubble. The author's verdict is that AI is a foundational technology on par with the Model-T, and that no single company, including Nvidia, needs to dominate for the underlying infrastructure shift to be real and lasting.

• Eisen advises Sophie not to try changing Frost's name, recalling that an early US attempt to call him "Will" didn't take. She says this particular adjustment won't be necessary.
• She encourages making fun of Frost's self-deprecating humor and Britishisms rather than taking him too seriously. She frames this as part of what makes him an easy, enjoyable co-anchor.
• She highlights debate as central to their on-air chemistry, crediting Frost's preparation and strong views for making their joint segments memorable. She recalls their 5 a.m. show together as a particularly bonding experience built on both coming prepared.

• A technologists' oath should be an ethos, not an enforced licence. The host doubts an international oath is practical and asks about enforced checkpoints instead; Hare answers that she likes the Hippocratic oath precisely because it is not enforceable, unlike a driver's licence, and says the world does not need a rule that you cannot code without it.
• Medicine rebuilt its oath after doctors betrayed public trust. Hare points to the post-war Nuremberg doctors' trial, held because physicians were instrumental in the Nazi regime's killings, which prompted a reckoning in medicine and a reboot of the oath; she frames it as a case study in restoring trust to a trusted profession.
• "Maximise benefits, minimise harms" is the realistic standard. Alongside "first do no harm", Hare offers her book's mission statement as a more utilitarian rule: some harm may be unavoidable, so choose it mindfully and openly, with knowledge and consent from the people affected. She cites lawyers, accountants and the UK civil service ethics code as professions that already build ethics into training.
• Good invention starts from problems, not profit. When the host suggests tech's first rule is "generate ARR", Hare pushes back that this holds for companies but many innovators are tinkerers solving a problem (her example is scissors for left-handed people) who only then see the money, and she thinks the best work comes from that.

• AI boosts seniors and slows juniors, so hiring tilts senior. Mark cites an MIT paper from a few weeks earlier showing AI-first companies shifting away from early-career hiring. He gives a rough figure of a 5–10x boost for experienced engineers against a 1.5–2x slowdown for early-career ones, who cannot tell when the AI is stuck. His example is a sleep that masks a race condition until it fails in production. He says customers tell him they see the same pattern.
• Coding agents are enthusiastic interns that never learn. Mark argues that agents repeat a corrected mistake days later unless it is in the instructions file, and a prompt file cannot hold every lesson. His conclusion is that juniors should no longer be hired to add capacity, since the agents now do that work, but to learn, accepting that they will be slower.
• Focusing only on boosted seniors is short-sighted for the industry. In the paper they are writing, the hosts propose a formal, AI-enhanced transfer of knowledge from seniors to juniors. Hanselman's version gives seniors a title such as "preceptor" and rewards them for the juniors they raise. Mark says internal Microsoft discussions favour making this the senior's primary job, that a pilot is starting at Microsoft, and that it takes about three years, not 90 days.
• Startups shouldn't hire early-career engineers; larger firms must widen the base. Mark says small companies don't need a talent pipeline, and that as agents spread he would not put juniors in a startup. Medium and large companies with complex, long-lived systems should hire roughly four juniors per senior, expecting some to leave for startups or quit the field.
• Juniors need tutor-style models and AI-free core coursework. Mark says Microsoft is discussing with GitHub agents that ask a junior to sketch a function first or explain the generated code, modelled on Khanmigo. He wants the main body of CS teaching done without AI. He cites an MIT study in which essay writers using ChatGPT could not recall their essays an hour later, while unaided writers still could a week later.

• The book exists because builders were given no ethics training. Hare's first tech job, in 2000 at Accenture, came with about two weeks of training and no discussion of ethics, data protection, security or supply-chain failure, so Technology Is Not Neutral (February 2022; the host says the Financial Times named it a best technology book of 2022) records lessons she learned on the job.
• The book is already dated by generative AI. Hare calls it a historical artifact: generative AI is absent, AI is treated only cursorily, and climate and sustainability are missing. She has discussed an update chapter with her publisher but thinks it is too soon, and notes the UK's digital-ID plans revive her chapter three.
• Platform deplatforming questions persist with the sides reversed. The book opens with Twitter's Jack Dorsey removing then-President Trump after the Capitol attack; Hare argues the question of removing an elected official is still live, now posed under "Trump 2.0" with liberals rather than MAGA figures being cancelled.

• Eisen says the common thread among the best leaders she's interviewed is a rare balance of vision and granular detail. Across both business and government, she says the standout trait is holding a big-picture sense of where an organization should go while simultaneously knowing the operational specifics well enough to answer questions about them.

• Lost Dog's founding claim: CEOs are overpaid by 30–50% a year. Tom Sosnoff says this applies to more than 98% of CEOs at the largest publicly traded companies, pegging the average S&P 500 CEO's pay at $21 million annually over a typical 7-year tenure — which he calculates as roughly $56 million in total overpayment per CEO.
• He claims the average employee is underpaid about 20% annually. Over a career, he says that gap totals $2–3 million per worker, and frames Lost Dog's mission around closing it — adding that he and co-CEO Scott Sheridan are taking no compensation from the company themselves.

• Technology ethics means maximising benefits and minimising harms of any tool. Hare defines technology broadly, including processes such as automating and manufacturing, and pictures philosophy as a Swiss Army knife whose six branches include ethics, so a stuck ethical question can borrow from the other five and from non-Western traditions. She contrasts France, where every pupil must pass philosophy to finish high school, with an Anglo-Saxon world whose tech workforces run ethics initiatives without that training.
• An oath for technologists should be an unenforced professional ethos. Hare likes the Hippocratic oath, rebooted after the Nuremberg doctors' trial, precisely because it is not mandatory; she wants ethics in the formation of engineers, as with lawyers, accountants and UK civil servants, and rejects any rule that you cannot code without it.
• Regulate harmful uses, not the tools themselves. Her fork analogy: eating and stabbing are both uses of a fork, and only the stabbing needs regulating, so rules should be few, unambiguous and easy to enforce. She argues regulation such as aircraft and car-seat standards is a guarantee and an accountability mechanism, not a brake on innovation.
• AI slop may finish off an internet that was never that good. Responding to the host's framing of "enshittification" and slop (he cites a recent HBR story on machine-written enterprise email), Hare suggests the internet may have to "burn itself down" before people return to books, libraries and in-person life. Her own fix is intentional use: social apps off her phone, newspapers read directly, more time with people, and going to see places herself because AI makes it hard to know what is real.
• The national grid cannot carry the government's AI ambitions. On the UK AI action plan, Hare says Britain has Europe's highest electricity prices, an old grid needing massive investment, a housing-style inability to build, and worsening heat waves (four this summer) for water- and energy-hungry data centres. She tells listeners to check in five to 10 years how many promised projects get built, and calls the political problem far harder than the engineering one.

• Break AI-job anxiety into a tiered skills hierarchy. Asked by the host whether cognitive work is no longer safe, McGovern, who is frustrated by clickbait angst, proposes tiers: basic prompting and chatbot use are table stakes. Above that come understanding LLM architecture, limitations, hallucination, bias and data hygiene, then keeping current with OpenAI, Anthropic and Google tooling, prompt programming and customised model workflows.
• Orchestration and integration are the next valuable layer. McGovern argues that, as in past decades, value comes from connecting tools, putting them into production and managing latency and cost, extending to multi-agent systems and tool chains. He cites an "automation paradox": automated work still needs human oversight and judgment.
• Human skills, domain knowledge and foresight top the hierarchy. Above engineering he places communication, collaboration, domain expertise (fintech, healthcare, law), AI strategy, ethics, safety and compliance, noting many people now pursue AI risk-compliance certificates. Above all he puts learning to learn, tolerating ambiguity and anticipating what AI will enable next.
• Sunset old skills deliberately and build your own brand. McGovern says skills' half-life is far shorter than before, so he resists loss aversion: after decades honing his coding, he now focuses on being the best prompt engineer he can and teaches coding fundamentals before shifting to prompting. With no one depending on one employer any more, he urges blogging, posting and building a personal brand.

• Eisen says she and the business leaders she respects most have "warmed" to tariffs. She was surprised that even small businesses absorbing real costs are willing to tolerate the pain because they feel someone is finally "fighting for American business."
• She reports tariff costs have been split more evenly than feared, among importers, foreign exporters, and consumers. This has avoided both a feared inflation surge and a major hit to profit margins, she says, while also adding a few hundred billion dollars a year to Treasury receipts.

• Startups preview tomorrow's industry-standard skills. McGovern, a venture partner at Cortical Ventures, calls AI startups "time machines": they hire for flexibility, multiple roles and coachability rather than static résumés, and those bets tend to become standard practice later.
• AI lets startups run as "tiny teams". He describes small, highly capable teams with hybrid skills, because AI now augments or automates routine and some expert work: legal help via chatbots or legal platforms, and an MVP demo for VCs built in a day with tools such as Replit and Lovable. Founders therefore prioritise fewer, higher-quality hires with domain expertise.
• Chasing revenue per employee is unhealthy, he argues. McGovern cites, from memory, Lovable reaching 10 million in revenue in two months with about 15 employees and Cursor reaching 100 million with 45 people, which he partly dismisses as "a wrapper around an LLM" while crediting its training work. He says Cortical itself was set up to use AI to build an AI VC firm.

• University AI curricula lag far behind the field. The host relays a LinkedIn post by OpenAI researcher Noam Brown that intro-to-AI courses teach decades-old ideas such as hill climbing rather than LLMs and transformers, and says that, especially at US prices, a degree may not be the best use of capital for employable skills. McGovern agrees, while granting that universities must teach durable fundamentals.
• Banning ChatGPT was the wrong response; teaching its use is right. McGovern faults universities for banning ChatGPT rather than guiding students with it, and has built AI into his own ODSC bootcamp. He also cites an MIT Media Lab co-authored paper on "your brain and ChatGPT" as a warning that overuse erodes skills.
• Rising CS-graduate unemployment is not simply AI's doing. McGovern recalls a report putting computer-science graduates' unemployment at around 7–8% against 3–4% for another group, but attributes much of it to big-tech hiring by Apple, Meta, Google and a few others rather than AI. He concedes junior skills are easily replaced by AI and says he would hire a junior graduate eager to learn AI over one dismissing vibe coding as a trend.
• Some universities are catching up, he expects. He names Northeastern, BU and BC as doing well and says the shift to skills-based hiring is real.

• A denied benefits applicant attacking recipients shows resentment, not principle. He plays a clip of a conservative single mother who was turned down for assistance and then told recipients to "get a condom and a job", though she herself has children she says she cannot afford; he reads her as jealous of those who got help.
• Many Americans now resent anyone who has what they lack. He argues the same people dislike both the hard-working successful and those who need help, lacking both gladness for success and compassion for need, and calls this self-centeredness one of America's big problems.

• Private letter ratings run 2.74 notches higher on average than NAIC's own SVO designations. Small raters (Egan-Jones, HR Ratings, Kroll, Morningstar) issue ~7,000 private letter ratings against ~1,000 from Moody's/S&P/Fitch combined; 79% of re-ratings move higher, some by more than six notches, letting insurers book investment-grade capital treatment on debt that isn't.
• US insurers hold roughly 35% of assets in private credit — CRE, private placements, residential mortgages, ABS, mid-market lending, and infrastructure — a far deeper concentration than the rest of the world, while loans (unlike bonds) carry no ratings requirement, so the private letter system fills the gap the big three agencies don't cover.
• The inflated ratings amount to capital arbitrage: a higher notch means less reserve capital required by law. Global Atlantic (KKR-owned), MassMutual, and Brookfield hold 55% of the highest-rated private letter bonds; following Tricolor and First Brands' collapses, the author reads this as evidence of systemic fraud risk despite bank claims the failures were "one-offs."

• The NBA gambling indictment is a symptom of gambling's institutionalization, not an isolated scandal. With 38 states plus D.C. having legalized sports betting, the indictment describes mob-tied defendants, rigged poker games with hidden cameras, and NBA head coach Chauncey Billups allegedly tipping bets and losses — evidence that mainstreaming betting has eroded the line between competition and manipulation.
• The media covering the scandal profits from the same betting culture it reports on. ESPN ran betting-odds ads on the same broadcast where Stephen A. Smith criticized the FBI's indictment timing, and Bill Simmons's podcast opened with a gambling ad before analyzing the scandal — an incentive conflict the author says keeps commentators from criticizing betting's spread.
• Former players Damon Jones and others are accused of using nonpublic injury information to tip bets, echoing the Pete Rose precedent. The author argues this isn't new human impulse but new frequency and access: a bet or tip-off is now a phone swipe away, scaled by technology beyond what a bookie-era gambler could manage.
• The fix is regulation and disclosure, not prohibition. The author, a former bank legal/compliance employee, proposes treating sportsbooks like banks — stricter oversight of prop bets tied to player performance, manipulation-detection systems, "Know Your Customer" restrictions (e.g., barring stadium employees from betting on their own team), and public education about odds, addiction, and corruption risk.

• The host chose the DeskPi RackMate for his 10-inch studio rack. He picked the 8U model after research; it lists at $119 MSRP in black or silver, with a 4U version and accessories, and he says the video is not sponsored and he bought it himself, though he adds an affiliate link.
• Assembly was easy and the kit complete. He reports it took under 30 minutes with clear instructions, and that it ships with a shelf plus a separate shelf for single-board computers such as Raspberry Pis; he 3D-printed a mount for his Comet PoE KVM and plans to move his studio network into it later.

• Agent mode trades Ask mode's safety for the power to edit files. Continuing from Part 1 of the Python module of Microsoft's "Mastering GitHub Copilot for Paired Programming" course, Giard works in its prebuilt GitHub Codespace, where the Copilot chat window has a drop-down for Agent, Ask or Edit mode. Ask mode, used in sections 1 and 2, by default creates and modifies nothing. Agent mode can change your files, so he says you want to keep an eye on what it is doing.
• Files in the chat's context get Copilot's constant attention. Files open in the editor are added by default, and others can be added with the plus button or by dragging them from the File Explorer. With no file in context it should look at the whole repository, so Giard advises adding the files most important to a prompt to scope it.
• Agent mode turns a multi-step prompt into a to-do list. Asked to fix code structure and comments, add consistent error handling, input validation and API versioning, write unit and integration tests, document the project, and make it deployment-ready, secure and faster, it drew up six to-dos and worked through them in turn. Proposed changes show as green (added) and red (deleted) lines until accepted with "keep". The demo added validation code, a tests folder and more documentation, and the API page still ran on port 8000. Giard says he would not send all of this as one prompt in production, but would run the prompts one at a time.
• Agent output is non-deterministic and still needs a human check. Giard says this was his fourth run of the section and each gave different results; the day before it ran for about half an hour and made much bigger changes. His view is that it is not necessarily correct, so you should run, compile and read the code and understand it before accepting it, even when using it to learn Python, and that AI is not going to take your job yet.
• Instruction files set the standards Copilot applies when generating code. A Copilot instructions markdown file in the project's .github folder sets guidelines such as project purpose, technologies, coding style, naming conventions, the PyTest testing framework and the mocking framework, and applies to every file in the project. For rules that cover only some files, a file such as apiroutes.instructions.md in a .github/instructions folder carries an "apply to" pattern at the top. In the demo it limits the rules to Python files in the webapp folder, for type hints, docstring format, parameter names and accessibility.

• Microsoft is retiring Azure Data Studio to focus on VS Code. Robles, a principal product manager on Microsoft's SQL developer experiences team, says the retirement was announced in February "this year" and that by the end of February next year there will be no patches, updates or new development. His reason is cost: ADS is a fork of VS Code, and maintaining both was too taxing when VS Code has, by his figure, more than 50 million daily users.
• The MSSQL extension is deliberately not a drop-in replacement. Robles puts the shared experience at "probably 90%". Some habits break (F5 opens the debugger in VS Code rather than running a query, though key bindings can be remapped), and ADS's admin extension with SQL Agent and SQL Profiler is not coming over, because the team targets the developer persona and cut features whose adoption was low; he says Agent and Profiler are highly requested and something might be done via GitHub Copilot.
• The extension, out since 2017, got real investment only from November 2024. Robles says the push began at Ignite in November 2024 with a new UI (connection dialog, query results, query plan analyzer, table designer), then schema compare and a schema designer that edits tables visually and emits the T-SQL; the UI went GA in May alongside GitHub Copilot support.
• Copilot gets database context through an @mssql chat participant. In ask mode it needs an open connection; in agent mode the agent discovers the extension's tools itself, lists connections, picks the server and database and acts, sometimes wrongly unless hinted. It runs on the SQL Tools Service back end, and Robles says Microsoft stores no prompts or PII and has no telemetry beyond reported errors and thumbs-up/down ratings.
• The roadmap closes the ADS gap, then makes AI proactive. Shipped recently: SQL Server containers in a couple of clicks (SQL Server 2025 reached public preview in May) and browsing and provisioning SQL databases in Fabric. Planned or under consideration: backup and restore, edit data, DACPAC export/import, a table explorer, Azure SQL provisioning, AI offering help when a query runs over two minutes, Copilot in the schema designer, and Data API builder integration; he stresses none of it is set in stone and asks for feedback.

• Aggregate data show no AI jobs apocalypse. The host notes US job creation slowed to 20,000 in August from 160,000 in April, but cites Yale's Budget Lab (October) finding no major shift in the kinds of jobs people do since ChatGPT's late-2022 debut, and a stable share of the white-collar jobs most exposed to AI.
• Payroll data show young workers in AI-exposed jobs losing ground. He reports Stanford research by Erik Brynjolfsson (August), covering payroll records for over 25 million workers: employment of 22–25-year-olds in AI-exposed occupations fell 13% since late 2022 while older colleagues in the same jobs grew about 6–9%, and software developers aged 22–25 fell nearly 20% by this summer. Brynjolfsson's explanation, as relayed, is that LLMs learn from written material like university study, while older workers hold tacit knowledge never written down.
• Junior hiring fell faster at firms adopting generative AI. Two Harvard researchers used AI to parse 200 million job postings, tagging about 10,000 firms hiring "generative AI integrators" as adopters against 280,000 control firms; junior positions fell 8% more steeply at adopters after 2023, with no gap in senior hiring. Mid-tier university graduates fared worse than top- or bottom-tier ones, which the host reads as firms keeping top recruits for skills and bottom-tier ones for cost.
• The entry-level market is splitting by AI skill. Per the host, entry-level workers with AI skills saw salaries rise 12% year on year, while recent reporting says Goldman Sachs and Morgan Stanley executives are weighing cuts of up to two-thirds in junior analyst hiring. His advice is to build skills that complement AI, gain deep expertise, or lean on interpersonal skills.
• Adopters are still few, so the effect may grow. The host stresses that only about 10,000 of almost 300,000 firms in the Harvard study were AI adopters, and expects the impact on the data to grow as adoption spreads.

• Marks argues investors should never buy an asset simply because it's rising or expected to keep rising. He says it must represent good value instead, invoking economist Herbert Stein's line that "if something cannot continue it will stop."
• He says genuine contrarian calls are rare, not a repeatable strategy. Working on his second book with his son Andrew, he realized his own market calls were right largely because he found the market "crazy high or crazy low" only five times in 50 years — simply inverting the crowd is, in his words, a fast way to go bankrupt.
