David's Saturday AI Thoughts
WHAT HAPPENED THIS WEEK * One activist letter froze a board's AI workspace overnight. The doctors are next.: From David's week helping a hundred non-executive directors: one board's AI workspace went dark the morning an activist investor asked for its contents to be made discoverable. The Conference Board's April survey finds two-thirds of directors use AI for board work while barely a quarter of executives call their board highly fluent, and the Medical Protection Society warned that doctors and the NHS could be sued over AI tools' mistakes, with the clinician left as the 'liability sink'; it wants AI reclassified as a product under the Consumer Protection Act 1987 so liability flows to developers. The governance frontier is moving from 'can the data leak' to 'who owns the answer when the model is wrong', and the CEO'd policy (every output checked, edited and owned by a named human) is the only good answer to both the letters and the writs. * Meta built a 'second brain' that 63,000 staff installed in three months. It started with one person.: Meta's analytics team reports that an internal AI tool one of its data scientists started has been installed by 63,000 employees within three months, with no top-down mandate and no transformation programme. One person built something useful and the rest of the company found it. The standing question for readers: what are you doing to encourage and enable this at your firm? * When cheap models do make sense.: Ethan Mollick argues for hierarchies in which smart models supervise cheap ones: the smart one checks the plan, the cheap one does the volume. Right for machine pipelines running thousands of low-stakes calls; for your own judgement work, the essay's time-saved maths says buy the best. The item is the deliberate counterweight to the essay's argument, marking where it does and does not apply. WHAT TO TRY * Ask the AI to write the marking scheme before it writes the answer.: Ben Yoskovitz, a non-developer who ships production software with AI, has the model write three to five specific pass-or-fail checks before any non-trivial task, approves them, and then has the AI do the job, grade itself against each check, cite the evidence and stop the moment one fails. Ninety seconds of discipline against the long loop of 'looks good' followed by 'wait, no it isn't'. * Plan in one session, then start a fresh one to build.: Tiago Forte treats the first AI session as planning-only when the goal is a concrete document or deck: work out the brief in chat one, never let it start drafting, then open chat two, paste the brief and build. A clean start gives a sharper model, the deliberate stop tests whether the brief holds together, and a crash in session two still leaves you with the brief. * Keep your AI project lean.: Someone at a training David ran asked why their Claude project had slowed over a few weeks; they had been piling reference files into it. The model reads everything in a project on every request, so book fifteen minutes on a Friday to prune, and never leave fat PDFs in there: have the model convert each one to plain text first, since PDFs burn far more reading capacity than the same content as text.
