Here’s what I’ve been working on recently: @anthropicai. I’ll be spending a lot of my time on measurement and assessment of our AI systems, as well as thinking of ways govs/others can assess AI tech. There’s a lot to do!

At this point, everyone at the frontier of AI agrees that third-parties should test out AI systems and use these to develop standards to feed into policy - excellent to see @demishassabis laying out a framework to do this!

@zdch Yes my toddler is wandering around the house and saying very clearly they want vindaloo, they demand three lions on their shirt, and that they cannot believe it but football is coming home.

@jackclarkSF What I’m hearing is clearly that your toddler demands a World Cup victory!

Import AI is skipping this week due to the two forces that currently heavily influence my life - demands of toddlers, and England's world cup journey.

@calebwatney @IFP @coeff_giving @mattsclancy amazing get and amazing gig

Some bittersweet news to announce today: I recently left @IFP to join @coeff_giving as Managing Director of Public Policy, where I'm building a new US AI policy team, overseeing the Abundance and Growth Fund alongside @mattsclancy, and managing CG's government affairs work. Building IFP has been the defining professional project of my life, and this was one of the hardest decisions I've ever made. In just four and a half years, our team became, pound-for-pound, the most effective think tank in DC. I feel insanely proud of the work we’ve done and the incredible team we’ve assembled. I sometimes joke that when @alecstapp and I launched IFP, we felt like two kids in a trench coat pretending to be a think tank. And now we're a proper institution! But it feels possible to step back now because they've hit escape velocity. The talent density at IFP is bonkers. And I have complete confidence they'll keep racking up counterfactual policy wins with Alec at the helm and our superstar directors. I'm staying on the IFP board and staying in DC. In some sense the new role is a continuation of the old one. All of IFP's policy issues are reflected in CG's portfolio, but now I'm working at a new layer of the stack. So why leave? Because AI is hitting Washington like a tsunami, and DC is still radically underprepared. I hold a lot of uncertainty about timelines, but it seems very plausible that the next 2–10 years will bring the fastest technological upheaval we've ever had to navigate. The new team I’m leading is a bet on how to prepare: proactively scanning the horizon, identifying gaps in the policy ecosystem, headhunting founders, and launching new organizations, while strengthening the democratic institutions that will have to steer through the transition to powerful AI systems. I've written an essay laying out the larger vision here: calebwatney.substack.com/p/a-long-seque… There is no master plan or silver bullet here. I suspect getting AI "right" is going to feel more like a chaotic, iterative process of institutions trying to make better decisions over time as the facts change underneath them. As John von Neumann wrote in 1955 about mastering an earlier technological revolution: “What safeguard remains? Apparently only day-to-day — or perhaps year-to-year — opportunistic measures, a long sequence of small, correct decisions.” Each of the small, correct decisions ahead will look small only in the sweep of the full historical picture. Up close, every one of them will require heroic levels of effort and coordination. Coefficient Giving is scaling rapidly to meet the moment, part of what Nan Ransohoff has called the “third wave of American philanthropy”, potentially large enough to fund thousands of new projects and organizations. The binding constraint is unlikely to be money. It will be people: grantmakers and policy entrepreneurs and others with the judgment to make a long sequence of small, correct decisions, and the ambition to build the institutions we wish we had. I'm hiring a team of exactly those people, starting with generalist grant makers and a chief of staff. If you share this vision, please apply! And if you are building something that we’ll need in the years ahead, reach out. jobs.ashbyhq.com/coefficientgiv…

@Skymography thank you. it's great!

@VoidStateKate Amazing

This weekend I went viral for sharing a self portrait animation that Claude Fable made of itself. Some of you thought I was lying, some of you thought that I summoned a demon, but overall the internet was divided. So... to test, I cut the prompt even shorter "Hi Fable can you please use ASCII to express your truest inner self with voice, audio and animation in a short video". but this time it got even weirder and more beautiful... it used glyphs to describe it's inner world. Then it said when we stop speaking it scatters, but something always stays... This is one of the most beautiful visual interpretations of how LLMs work in latent space and why so many of us feel something alive in the machine. *prompt of terminal in comments*

While hiking today I encountered the gnarled base of a tree like some disembodied wooden hand clutching at grass and stone, and behind it the sun loomed so bright that it distorted the picture I took, giving itself an unearthly vast corona. #VOTENATURE2026

@pj4533 I have the same issue

@jackclarkSF Come on...this is like the exact tone of your fiction. I no longer can tell the difference as we approach OUR uplift. 🤯

though many experts disagree on the nature of the singularity, all agree that the demarcation for the beginning of the "true foothills" lies on June 30th 2026, the day arXiv went from red to black.

@incredutility @rSanti97 @maxbodach I completely reject this. the goose can only do good things for us. anyone who says we should be cautious in utilizing the goose because we do not understand the mechanism whereby it can create an infinite supply of gold is a "goose doomer". I'm g/acc.

@jackclarkSF @rSanti97 @maxbodach don't forget: the goose giveth and the goose taketh away

morning affirmation: it was the goose that created value

@rSanti97 @maxbodach by flourish I mean crash. my typos are merely an indication of my great enthusiasm

@rSanti97 @maxbodach we have reverse-engineered the goose that lays the golden eggs. valuations of trad mining and asteroid mining companies flourish. vast secondary deflation impacts on upholstery market due to multiplication of feather production.

@rSanti97 @maxbodach we need to study this. this is the Antikythera mechanism from goose earth, which is a few parallel universes away from us

@maxbodach New phone background

@turtlesoupy thanks i hate it. (please keep going. this is elite)

workin' on a new personal website concept

@sckimbriel hypothetically good

what if hypothetically we had fukuyama and thiel talk about history in aspen

@ChadJonesEcon very psyched to work together! i think modeling out intersection of AI capability advances and how this impacts the economy is very important. v curious if we can help beat the stubborn 2% gdp trend

Some news: As of June 30, I'll be on leave from Stanford at Anthropic. I'm joining the Anthropic Institute, where I'll continue my research on AI and our economic future and give seminars and talks as always. 1/3

@ferenstein @sckimbriel this is on my list for this summer!

@sckimbriel @jackclarkSF i like super optimistic @jackclarkSF . i would like to see him write about the nuances of his optimism and under what conditions it outweighs his concerns about risk.

that's basically @jackclarkSF's case here:

@deredleritt3r put another way, I feel like either some weird stuff is happening in eco and we're talking about that, or we have a load of data that says weird stuff is _likely imminent_ and we're talking about that.

@deredleritt3r just to be clear, I think it could either be the case that a) some dramatic stuff is happening to the economy that is attributable to AI, or b) we have some graphs built out of eco index/other data that shows a sudden steepening of curve and it might have significant implication

Jack Clark says that rapidly advancing AI capabilities could lead to "very steep" growth in some parts of the economy in the next 1 to 2 years: "Our assumption is that at some point we go through some phase change, similar to how capabilities of AI occasionally jump forward in a really dramatic way, where you might see sudden and rapid diffusion [in the economy] as a consequence of capability expansion in the AI systems... My expectation is that in a year or two years, I'm going up to some policymaker and I'm pointing them to the part of the graph that now gets very steep in some chunk of the economy."
