David's Saturday AI Thoughts
WHAT HAPPENED THIS WEEK * AI can now find software vulnerabilities faster than humans can patch them. Discovery is no longer the hard part; verification is.: A frontier model handed to fifty cybersecurity partners (Anthropic's Glasswing initiative) surfaced more than ten thousand critical or high-severity vulnerabilities in the systems it was pointed at. Cloudflare has roughly four hundred major bugs to work through; Palo Alto Networks shipped five times more patches than its usual release cadence. Maintainers have asked the developers to throttle the discovery rate because there are not enough security professionals to close the gaps before attackers find them. Software security used to be limited by how fast new vulnerabilities could be found. It is now limited by how fast humans can verify, disclose and patch them. * A general-purpose AI model has autonomously disproved a 1946 conjecture in geometry. Independent mathematicians have verified the proof.: OpenAI handed a general-purpose reasoning model a long-held belief tied to a 1946 planar unit-distance problem of Erdos, the prolific Hungarian mathematician, and the model produced a disproof. Other AI models have since solved further long-standing problems; the wrinkle is that the others were purpose-built for mathematics. OpenAI's was not. Machines now clear the tractable tail of problems fast, pushing the human frontier towards what still resists them. After AlphaGo beat the world's best human Go players in 2016, the skill of human Go players noticeably improved. Noam Brown, an OpenAI researcher who helped build its reasoning models, suspects the same pattern will play out in maths. And then, perhaps, in business. * Generative AI use among American adults has hit 58 per cent in four years. The personal computer took sixteen years.: The Federal Reserve's February 2026 Real-Time Population Survey of working-age adults puts overall adoption at 58 per cent, up from around 45 per cent in October 2024 but recently flat. Work use is 44 per cent. Non-work use is 51. Daily use sits at 14 per cent and saves an estimated 2.2 per cent of total work hours. Alfred Lin, a partner at Sequoia Capital, notes this is the penetration level the personal computer took sixteen years to reach: a four-fold acceleration on the closest analogue. The caveat is the plateau. The early-adopter phase is over. The hard part starts. WHAT TO TRY * Ask the model what else it needs to know: The most productive sessions David sees with senior leaders don't open with a clever prompt. They open with the user pasting context — role, situation, what they're trying to do — and then asking two questions. First: "what else do you need to know about me to help me well?" Second: "what could you do for me right now that I haven't asked for?" The first surfaces gaps the user wouldn't have spotted. The second produces use cases the user didn't bring. The blank-prompt paralysis dissolves. * Either AI challenges you at the start, or you challenge AI at the end. Don't skip the challenge.: A leader David sat with this week had let an AI output stand without pushing back. Two patterns work and one fails. You can challenge before the model starts: share your point of view and ask the model to challenge it, force it to surface holes and the strongest counter-argument. Or you can challenge after the first draft: force a rewrite, name what's wrong, make it earn the second pass. The pattern that fails — and the one David sees most — is read-and-accept. * Ramble into the microphone, let the machine find the structure: A managing director David coached this week outlined obsessively: 700 words of outline for a 1,500-word article. The cost of structuring before writing was eating his weekend. The fix was inverting the order. Pick up your phone, dictate the mess, paste the transcript into your model, ask it for the through-line. Structure becomes the cheap thing. Particularly powerful for executives who think by talking — more common at the top than people admit.
