A Substack essay from the Side Work newsletter built on direct conversations about pay, showing what people in different roles actually earn and how they talk about it.
Why I recommend it: Real numbers from real people beat any salary calculator. Use it to set a floor before your next negotiation, and notice how plainly these folks discuss money.
Analytics and Excel teacher helping professionals build real data skills and use AI to increase their impact at work.
In plain terms: An Excel MVP and author teaching practical analytics skills you can apply at work, including how to pair them with AI tools. Self-paced and beginner-friendly.
From the site: Helping you build real-world analytics skills so you can partner with AI to accelerate your impact at work. Author, LinkedIn Top Voice, Microsoft Excel MVP.
Why I recommend it: A good fit if you want data skills without a bootcamp. His lessons are built around work you actually do in a job.
Ben Hylak argues that as AI agents start negotiating with each other on our behalf, our privacy will depend on how well those agents handle social situations.
Why I recommend it: An opinion essay by a startup founder, not research. Good prompt for thinking about what you let an agent share.
I believe the time has come for a broad boycott of generative AI — a public argument from AI researcher and critic Gary Marcus on why the technology is not ready for widespread deployment.
From the site: I believe the time has come for a broad boycott of generative AI — a public argument from AI researcher and critic Gary Marcus on why the technology is not ready for widespread deployment.

An essay weighing the argument that AI adoption could push unemployment into double digits, against the labor data we actually have so far.
Why I recommend it: I collect both the alarmed and the skeptical takes on AI and jobs on purpose. Read this next to the Census and Brookings data in this collection and form your own view rather than borrowing a headline.
Free Substack newsletter by a principal cybersecurity engineer sharing career tips and cybersecurity news, including a recurring 14-day U.S. cyber threat forecast (e.g. the September 22, 2026 VECTR-CAST report on actively exploited Cisco, ScreenConnect and VMware vulnerabilities).
Why I recommend it: Good for people moving into cybersecurity who want a practitioner's read on current threats. The threat levels and forecasts are the author's own analysis, not an official CISA rating — cross-check CVEs against the CISA KEV catalog.
Gary Marcus's free newsletter post on the September 23, 2026 UN Security Council briefing where Yoshua Bengio, Sam Altman, Dario Amodei and Hugging Face's Clement Delangue spoke. He reprints Bengio's remarks in full (with permission) and argues the speakers agreed on pre-release safety testing, transparency audits, liability, international cooperation and immediate action.
Why I recommend it: An opinion newsletter written the same day, not a full transcript. Marcus is a long-time critic of AI companies and says the speakers agreed with points he has pushed for years, so read it as his take. Only Bengio's speech is reprinted in full.
Technical newsletter by Vinoth Govindarajan taking AI agents apart: control loops, memory, orchestration, evaluation and what breaks in production. Recent series walks through the OpenCode architecture end to end.
Why I recommend it: Free to subscribe, over 2,000 readers; written for people who build software, not for beginners. Substack publications can add paid-only posts at any time, so check the top of a post before counting on it.
Manoush Zomorodi (NPR's TED Radio Hour) coins p(joy) as a deliberate counterpoint to p(doom), the probability-of-catastrophe number traded around AI circles: instead of estimating disaster, estimate whether satisfying moments are increasing in your life and what reliably creates them. The second half is a long interview with Brian Elliott of Work Forward on knowledge work right now — identity loss as machines take a skill you spent decades building, cognitive overload from supervising AI agents, and executives privately saying their best people and heaviest AI users are the likeliest to quit. Elliott's summary: human-led, AI-enabled, because nobody's competitive advantage is being average faster.
Why I recommend it: Read this the next time an AI doom number is quoted at you as though it were measured. The piece cites Gizmodo's plain point that no one at the frontier labs has an actual method for producing a p(doom) figure. The useful part is Elliott's three patterns in companies getting value from AI: a scorecard covering business impact, quality and employee engagement rather than tool usage; aiming at teams instead of individuals; and leaders using the tools in public, mistakes included. Free to read in full, no paywall.

A newsletter for university students and early-career professionals on building a career deliberately: networking with low effort, building a portfolio when you are not an artist, reputation-building as a young professional, early-career growth rules, job hunting after graduation, and working in and around AI. Launched in early 2026. Every issue in the recent archive is free to everyone, and the whole archive is open.
Why I recommend it: Best for the first few years of a career, where the advice gap is widest — the pieces on networking and on building a portfolio without being a designer are the ones to start with. It is one writer's experience rather than researched guidance, so treat it as a practitioner's notes: take the habits, check any claim about hiring against a source that publishes its numbers.
Publishing platform for newsletters, podcasts and video. Free to start and publish with no fees until you choose to charge readers; Substack takes 10% of paid subscriptions if you do.
From the site: The app for independent voices
Why I recommend it: Free tier covers everything you need to publish and grow; you only share revenue if you turn on paid subscriptions.
Substack from historian Rutger Bregman on moral ambition and doing work that matters, aimed at people considering a career built around impact.
From the site: Historian | Author of ‘Moral Ambition’ (2025), ‘Humankind’ (2020) and ‘Utopia for Realists’ (2014) | Co-founder of The School for Moral Ambition. Click to read Rutger Bregman, a Substack publication with tens of thousands of subscribers.
Why I recommend it: Directly relevant if you are rethinking what your career is for. It argues a position hard; take the questions, not the prescriptions.
Ed Elson's Simply Put essay on how AI, cost and weakening returns on a degree are reshaping education and the entry-level job market.
Why I recommend it: Useful context if you are deciding whether more school is the answer. It argues the credential is worth less than the proof of work.
A free newsletter briefing on AI developments from a pro-human standpoint, covering labor, safety, policy and the campaigns pushing back on automation-first decisions.
Why I recommend it: A steady weekly read if you want the human-impact side of AI news rather than product launches.
A practical walkthrough of building a good slide deck with AI: what to hand the model, what to keep yourself, and how to avoid the generic deck AI produces by default.
Why I recommend it: Decks are where AI output looks laziest fastest. Use the prompts here for structure, then write the words yourself.
A Substack essay from Prof. Pilyoung Kim on a recent study showing that warning users about sycophantic AI changes how they judge it — but not how much it shifts their views.
Why I recommend it: A sharp reminder that AI assistants can shape our opinions even when we know they are agreeing with us; relevant to anyone using AI for research or decisions.
High-trust talent referrals from top founders, operators, and VCs. Built for fast-growing startups.
Why I recommend it: A referral-driven newsletter for people who want to break into high-growth startups through trusted introductions. If you're tired of cold applications, this is worth following.
A newsletter analyzing what actually performs on LinkedIn and social platforms, based on running experiments and reporting the data rather than repeating best-practice folklore.
Why I recommend it: Most LinkedIn advice is guesswork dressed up as expertise. This one tests things and shows the numbers, which is why I read it.
Prompting framework and twelve worked prompts for using a top-ranked model on finance and analysis tasks.
Why I recommend it: Steal the prompt structure, not the finance specifics. The same framing works for market research or competitor scans in your own business.
Economist Noah Smith's newsletter covering labor markets, technology, industrial policy, and the economics behind AI hype cycles.
Why I recommend it: One of the few writers I trust to check the numbers before drawing a conclusion. Worth a standing subscription if you follow the economy at all.
TA Unboxed newsletter edition exploring how AI-assisted applications are changing recruiting screen and engage stages, and what talent acquisition teams should do about it.
Why I recommend it: Read this to understand the recruiter's side of the desk. The same AI tools candidates use are flooding their applicant tracking systems, which changes how you should stand out.
Guide arguing that nearly every paid job-search service has a free equivalent, with the specific free resources to use instead of coaching and resume packages.
Why I recommend it: This is the whole premise of this library too. Spend money only after free help has run out, not before.
Psychologist and professor Jacqueline Nesi translates new research on technology, attention, and mental health into practical guidance for digital life.
Why I recommend it: A research-backed counterweight to hot takes about screens and AI. Good source material if you write or speak about technology and people.
Newsletter breaking down system design and backend engineering concepts with clear diagrams — interview-grade explanations of how large systems work.
Why I recommend it: Use the diagrams as interview prep. If you can redraw one from memory and explain the tradeoffs out loud, you are ready to talk about it in a system design round.
Newsletter testing and comparing AI coding tools and prompts, with side-by-side results for developers.
Why I recommend it: Skip the hype cycle and read the comparisons. Pick one tool from a recent test, use it on a real project, and write up what happened.

From the site: Where it all starts
Why I recommend it: Start here before rewriting your whole profile. Keywords in your headline and About section do more work than clever wording.
