There's lots of discussion about a16z dropping the word 'crypto'. It's actually a sign of crypto winning. It's outgrown being a standalone sector and now runs through global finance and frontier tech: payments, trading, tokenization, AiFi, and much more. We've spent more than a decade building this industry to make it useful everywhere, and we should welcome it escaping its own category. People used to say 'internet companies' - which is a prehistoric phrase now. Eventually, calling something a 'crypto company' should feel just as redundant. Many of us (including me) will keep the word. But the millions, and soon billions, using it every day won't care what we call it. They'll care what it lets them do.

I wonder how many good ideas we dismiss because they are not "practical". There is value in pushing the frontier for its own sake. It's exciting and motivating to work on (and also great marketing).

We were able to fine tune an open weight model (Qwen3.5-9B) on proprietary internal data at @coinbase, and it out performed frontier models, at much lower cost and speed, for a specialized task (fraud prevention in this case). I think we'll see more of this pattern inside companies. The frontier models are amazing generalists. But increasingly you'll see specialist models out perform on more narrow tasks, either working on teams, or by themselves. We're making it easy to fine tune models internally for our employees. We even have a skill for it in our internal harness that makes it easy to spin these up and start training them: "/fine-tune-and-serve-llm I want to fine-tune Qwen for payments risk review. help me get started" I imagine we'll have some backend services that could be replaced entirely by this new architecture.

We started running "pirate and architect" pods at Coinbase back in May of this year and I used this slide to talk the team through it. It works. 1 pirate, 1 architect, and a part-time designer. It lets each archetype lean in to their superpower and get more shit done without all the coordination overhead and "what if-isms". The pirate ships like mad, is product-minded and customer-obsessed. Always willing to throw-away code for a better version. The pirate is usually the DRI at the beginning too, working with customers, driving requirements, and a ship plan. The architect makes sure stuff is built for scale, takes the pirate's prototype, and drives its scale-out through spec for agents. The designer is building with both to constantly shape the experience and hill-climb to delight. There's a helpful mental model that I like: -Make it possible. -Make it reliable. -Make it delightful (or efficient). Previously, those 3 were done in a waterfall approach and was slow. Most people were just stuck on "make it possible." With agents and a new way of working, you have every opportunity to parallelize them and go 100x faster.

The coordination tax kills you. You are only as fast as the slowest part in the process. Just put someone who has the vision with an absolute maniac who just gets shit done

Tech is becoming a huge part of culture. Founders and engineers are role models, and I think that's a good thing. Kids should aspire to build something people want and contribute to society.

Must read
convergence to the mean when everyone looks at everyone else to decide what to make, we eventually stop making anything of our own. we copy what works. borrow the language, the aesthetic, the features. we call it learning from the market, following best practices, staying competitive. together, everything starts to feel familiar. polished, interchangeable. nothing wrong. nothing alive. the mean isn’t necessarily bad. it’s where everything lands when we remove the reasons for it to be different. numbers are easier to compare than feelings, so we make things that produce numbers. we study what gets attention, then shape ourselves around it. eventually the feedback stops informing the work and starts authoring it. we’re no longer asking what we want to say. we’re asking what will be rewarded for saying. ai makes this loop frictionless. it can draw from more references than we could see in a lifetime. but access to every perspective isn’t the same as having one. it hasn’t lived a particular life that makes one detail unbearable and another beautiful. when we ask it to choose for us without bringing any intention of our own, we get something plausible, easy to approve. then we ship it, measure it, copy it, and feed it back into the next round. a tidal wave of mid. this changes not just the work, but the people making it. we describe ourselves in categories platforms can distribute and markets understand. designer. founder. creator. pick a niche. build a brand. be consistent. the parts that don’t fit become inconvenient, even when those contradictions might produce our most interesting work. we become easier to classify and harder to tell apart. i think we need to approach making things more like artists. an artist develops a perspective through the work. making, noticing, choosing, failing, returning. learning what matters even when nobody else cares. craft gives that perspective a form precise enough for someone else to experience. the life outside the work matters too. the places you’ve lived, the people you’ve loved, the things you’re embarrassed to care about. these aren’t distractions from having something to say. they’re how you come to have something to say. we understand this with music, paintings, photographs, movies. we expect a person to be present in the choices. we want to experience something we wouldn’t have encountered without them. software can do this too. a piece of software expresses beliefs about how life should feel. what deserves your attention. what you should be free to change. whether a task should feel like paperwork or play. even a small interaction can carry someone’s care, humor, or curiosity. but we rarely talk about software as a medium. we talk about it as an industry. markets to capture, workflows to optimize, competitors to catch up with. we add a feature because someone else has it, without asking whether it belongs. products accumulate the same parts and lose what made them worth choosing. underneath the branding, it’s all the same thing. artists learn from others too. the question is whether you’re absorbing those influences into a point of view, or using them to avoid developing one. what are you trying to let someone feel, understand, or do? why this particular shape? what have you noticed that the existing tools don’t seem to notice? those questions don’t have answers you can borrow from a competitor’s roadmap. if we can make almost anything, deciding what deserves to exist becomes more important, not less. speed gives us more chances to exercise judgment. it doesn’t remove the responsibility. i don’t want a world where every person becomes a more efficient distributor of the same ideas. i want people to use these tools to go further into what they actually care about. to make things specific enough that we can feel someone behind them. what is the point of everyone being able to make something, if we all end up making the same thing?

Details win when everyone has the same tech.
we are seeing a come back of product management when it comes to the design and UX of personal agents. instinct / dot / muse / grok bot all have significant product work on tying together ux with model capabilities underneath and its access to various services. in all of these cases I rarely care about the underlying model but very much care about the big and little touches ( the muse activity notification, the little thumbs up emoji in Instinct to acknowledge a message and more). contrast this with the “upgrade to latest model” path we are otherwise on.
