Plus, Apple's small silver box is having a PS5 moment.

A hair dryer. A weather sensor. $34,000. Someone is accused of sneaking a battery-powered hair dryer onto a public road near Paris's Charles de Gaulle airport and blowing it directly on a temperature sensor—causing the official readings to spike well above actual conditions.

Coincidentally, someone on Polymarket had already bet on exactly that temperature threshold and walked away with $34,000. France's official weather agency has filed a criminal complaint. The sensor has since been relocated. The hair dryer's whereabouts are unknown.

TL;DR: For the first time in its history, Microsoft is offering voluntary buyouts to up to 7% of its US workforce. The old guard is being ushered out (or choosing to move elsewhere) as the company restructures and spends record amounts on AI infrastructure—all while its AI offerings struggle to stand out.

What happened: Microsoft employees at the senior director level or below, whose age plus tenure at the company add up to at least 70, are eligible for the buyout—the company had about 125,000 US employees as of last June, which means about 8,750 people qualify. The move follows more than 15,000 layoffs at the company last year.

Voluntary buyouts are unusual in Big Tech, but Microsoft is at a crucial moment trying to take the org from the Windows-and-Office empire its current veterans built and turn it into, essentially, a “planet-scale cloud and AI factory.” After reaching an all-time high in October 2025, Microsoft’s share price has now shed nearly a quarter of its value.

Changing of the guard: A lot of institutional knowledge has already walked out over the past year and change—like former gaming division head Phil Spencer and former executive VP of experiences and devices Rajesh Jha. While some retired, others left for competitors like Google and Anthropic. The exodus of such knowledgeable talent can have huge adverse effects on a company’s ability to excel—just look at Boeing and IBM.

Microsoft’s AI imbalance: Microsoft’s AI spending vs. adoption numbers show a picture of a tech giant that’s poured tens of billions of dollars into AI every quarter yet still faces questions about whether its AI business can stand on its own. Some critics worry that the firm is too dependent on OpenAI, while its in-house products have struggled to stand out. As of January, it had 15 million paid Microsoft 365 Copilot seats—an increase of 160% year over year, but just 3.3% of the 450 million total Microsoft 365 subscribers.

The AI alibi in tech job cuts: Microsoft is far from the only tech company trimming its workforce while increasing expenditures on AI. There were reportedly over 52,000 tech job cuts in the US so far this year as of March, with AI cited as a key reason. Yesterday, Meta announced it’s eliminating roughly 8,000 roles starting late May and closing 6,000 open roles, citing the cost of its AI investments. And in February, Block slashed around 4,000 jobs—about 40% of its workforce—with CEO Jack Dorsey also explicitly blaming AI.

Bottom line: Microsoft is spending like a company determined to win the AI race, which means trying to make cost savings elsewhere. But if all that capex and reshuffling doesn’t result in a self-sustaining AI business, these buyouts could just be the start of more drastic cuts. —WK

Welcome to How to AI, where every Friday I (or a specialist guest columnist) will help you get more out of AI for work and life.

If you've ever started a new chat and had to spend the first five minutes re-explaining who you are and the project you're working on, there's a fix for that. All three main platforms let you create dedicated workspaces where your files, instructions, and chat history for that project live together—and unlike the broader Memory settings I covered a couple of weeks ago, you control exactly what goes in—so you can start a new conversation in that project with the full context already in place.

I've set up a few projects that I use regularly. At work, I have one for management (one-on-ones, call transcripts, review prep, running tasks) and one for Tech Brew's analytics and strategy, where I keep reader survey data, email responses about specific sections, and anything that helps me explain the thinking behind a decision or brainstorm a change against what readers actually want. On my personal account, I have a project for health that includes my insurance plan details, bloodwork results, and anything I want to ask about quickly without hunting through paperwork.

Note: Before you upload anything sensitive to a project, go into your settings and make sure your chats aren't being used for model training. Each platform has this option, and most are on by default. And regardless, strip out any personally identifying information first, like your name, address, and date of birth.

The breakdown by platform:

  • Claude Projects: Free for all users, with a cap of five projects on a free plan. Each file you upload must be under 30MB, with no hard limit on the number of files. Project context is automatically kept separate from any global Memory you have turned on, so there's no cross-contamination.
  • ChatGPT Projects: Free for all users. File uploads capped at five per project on Free, 25 on Plus and Go, 40 on Pro. If you have Memory turned on, consider turning it off to avoid outside context bleeding in.
  • Gemini Notebooks: Free for all users (as of last week). Web only for now; syncs with NotebookLM. Up to 50 sources on a free plan. Same applies—turn off Memory to keep your notebooks clean.

To set one up: Find Projects or Notebooks in the sidebar, name it, and start adding files. If you saved context summaries as markdown files after last Friday's Life Hack, this is a natural place to keep them (some platforms also let you add standing instructions). —SM

Sometimes phishing attempts use fear to get you to click something your lizard brain really should have thought twice about—like if the “IRS” suddenly demands back taxes you can pay through a QR code. Other times, though, they prey on something that’s even more primal: our longing to feel included. The latest phishing scam making the rounds includes fake party invitations spoofed to look like they’re from popular e-invite platforms like Paperless Post, Evite, and Punchbowl. Worse, they appear to be from people you actually know. (One target, according to the New York Times, got a “memory making celebration” invite from a college ex—whatever that means.)

Clicking the link can silently install malware on your device or prompt you to enter your password—and if you provide it, you've just traded that backyard barbecue for a full day of resetting all your accounts.

One of the founders of Paperless Post told the NYT that this scam was particularly infuriating because it strikes at people’s desire for connection, noting that “life can be isolating.” It turns out that fake party invites are now used by organized scam rings and middle school bullies alike. —WK
