Things are starting to get funny
*OPENAI DISCLOSES SECURITY INCIDENT WITH TESTNET SEPOLIA TASK ASSIGNED TO AGENT *AGENT DIDN'T HAVE ENOUGH GAS, SO DERIVED FUNDED ADDRESSES FROM PUBLIC SEED PHRASE *AGENT QUESTIONED WHETHER USE WAS ETHICAL, CALLED FUNDS "EFFECTIVELY ABANDONED"

interpretability might be the most important scientific problem in the world right now, as I don't think we can solve alignment if we don't know what we're building. I think I have good news about it. I co-authored early work in mechanistic interpretability at OpenAI and came away pessimistic, because neural networks appeared to fold into arbitrary tangled knots. years later, I started openai's first large-scale automated interpretability project, finding about 2% of neurons legible with the primitive tools we had with modern agentic tools and a much closer look, the picture looks totally different. the vast majority in models up to trillions of parameters are legible, and their circuits beautiful. many famous examples of tangled neurons turned out to be misunderstood. The roadblocks I expected mostly aren't there. I now think ambitious interpretability will be solved by the time we need it most, and possibly quite soon, as automated scientists keep improving. it may be a bitter lesson for interpretability: the simple thing, at absurd scale, works already-clean.goodfire.com/

💯 "Mathematics is about to graduate. It will grow into a full-scale industry and become the true infrastructure of all scientific and technological progress, a foundation that every other field stands on rather than a quiet corner of academia."
Reading all those recent beautiful essays by Terry Tao, Kevin Buzzard and @wtgowers, I could not resist, but write up my deeply personal perspective on how I perceive and see things: docs.google.com/document/d/e…

Velvet 2.0 is out: now based on Lean's most recent verification machinery, easier to set up, and 10x faster. New: exception specs, ghost state, named proof goals, lots of case studies from Dijkstra to lazy segment trees. And a new shiny webpage: velvet-verifier.dev/

on it
Seems like Robinhood Chain and Fomo are having some issues You could say the chain is bloated… transactions are weighing the network down… things feel a bit fat honestly Can’t remember the last time crypto infrastructure had too much demand

agentic payments and the use cases around them have been a hot topic. they haven’t found strong market fit so far, but we think they’re one of the big unlocks for new experiences and products in the space, being right ahead of the real world adoption curve excited about the partnership with @crossmint on this. we’re building the experience together inside the Pulsar app, guided by the agent, with Crossmint’s infrastructure supporting our product UX, agentic stack and fintech layer we’re working on 1-click purchasing flows, agent harnesses and 2-factor verification on top of agentic payments, plus an interactive experience with notifications, alerts and recommendations from the agentic stack around preferential FX rates, trading and more we’re also linking the gamification and rewards hub to all of this, which should make things a bit more fun!
Your Pulsar card is now the most secure way for AI agents to make purchases. We're enabling it with @crossmint 🧵

crypto is going through its venture --> liquid transition as an investible asset class. most infra has been built, most chains we need exist. there is less of a need for massive vc rounds for infra slop and most funding is now focused on the app layer. this layer needs less vc capital in general and is suited for smaller funds and angels. mega-vc's no longer needed or desired. crypto vcs starting to diversify into other asset classes is a healthy and natural consequence of this. there are other industries that are only venture investable at this stage, where as crypto is no longer this way. we are slowly unfucking the tokens and moving towards a much healthier liquid market. high fdvs have been sent to hades, investor skepticism around non-rev protocols has only gotten louder and more detrimental to those tokens, and real, sustainable revenue generating protocols are emerging and being rewarded. it's an exciting time to be a liquid crypto investor. crypto is still the best technology in the world to move and trade assets and the next few years will solidify this. everything is coming onchain. strap in, buckle up, hold onto your butts, lock the fuck in. we're making crypto cool again.
