@dillon_mulroy Yeah. I can’t handle the rate of churn and constant refactor of my beliefs/process every week. I hope this period normalizes and gets ~boring again. Or at least lets us sit with our thoughts >1wk.

yall im ngl its way harder to get joy and satisfaction out of building with ai than it was before constantly straddling burn out, being far less immersed in hard problems, constant context switching i’m tired of the uncertainty of where this is going and how to do it well

@grah4m @wesbos +1 - I sometimes take for granted just how AI native our engineering practices are in relation to the broader industry. When I did this interview we were just ramping-up our tools. Today we have clear quality & productivity signals guiding us - And still so much runway!

A peek inside Coinbase’s AI software dev workflow. We recorded this in October when 50% was unfathomable. Seems low now. One of our most downvoted eps, one of my favourite eps. youtube.com/watch?v=x7bsNm…

This is an email I sent earlier today to all employees at Coinbase: Team, Today I’ve made the difficult decision to reduce the size of Coinbase by ~14%. I want to walk you through why we're doing this now, what it means for those affected, and how this positions us for the future. Why now Two forces are converging at the same time. We need to be front footed to respond to both. First, the market. Coinbase is well-capitalized, has diversified revenue streams, and is well-positioned to weather any storm. Crypto is also on the verge of the next wave of adoption, with stablecoins, prediction markets, tokenization, and more taking off. However, our business is still volatile from quarter to quarter. While we've managed through that cyclicality many times before and come out stronger on the other side, we’re currently in a down market and need to adjust our cost structure now so that we emerge from this period leaner, faster, and more efficient for our next phase of growth. Second, AI is changing how we work. Over the past year, I’ve watched engineers use AI to ship in days what used to take a team weeks. Non-technical teams are now shipping production code and many of our workflows are being automated. The pace of what's possible with a small, focused team has changed dramatically, and it's accelerating every day. All of this has led us to an inflection point, not just for Coinbase, but for every company. The biggest risk now is not taking action. We are adjusting early and deliberately to rebuild Coinbase to be lean, fast, and AI-native. We need to return to the speed and focus of our startup founding, with AI at our core. What this means To get there, we are not just reducing headcount and cutting costs, we’re fundamentally changing how we operate: rebuilding Coinbase as an intelligence, with humans around the edge aligning it. What does this mean in practice? - Fewer layers, faster decisions: We are flattening our org structure to 5 layers max below CEO/COO. Layers slow things down and create coordination tax. The future is small, high context teams that can move quickly. Leaders will own much more, with as many as 15+ direct reports. Fewer layers also means a leaner cost structure that is built to perform through all market cycles. - No pure managers: Every leader at Coinbase must also be a strong and active individual contributor. Managers should be like player-coaches, getting their hands dirty alongside their teams. - AI-native pods: We’ll be concentrating around AI-native talent who can manage fleets of agents to drive outsized impact. We’ll also be experimenting with reduced pod sizes, including “one person teams” with engineers, designers, and product managers all in one role. In short: AI is bringing a profound shift in how companies operate, and we’re reshaping Coinbase to lead in this new era. This is a new way of working, and we need to leverage AI across every facet of our jobs. To those who are affected I know there are real people behind these decisions — talented colleagues who have poured themselves into this company and our mission. To those of you who will be leaving: thank you. You’ve helped build Coinbase into what it is today, and I am sincerely grateful for everything you've done. All impacted team members will receive an email to their personal account in the next hour with more information, and an invitation to meet with an HRBP and a senior leader in your organization. Coinbase system access has been removed today. I know this feels sudden and harsh, but it is the only responsible choice given our duty to protect customer information. To those affected, we will be providing a comprehensive package to support you through this transition. US employees will receive a minimum of 16 weeks base pay (plus 2 weeks per year worked), their next equity vest, and 6 months of COBRA. Employees on a work visa will get extra transition support. Those outside of the US will receive similar support, based on local factors and subject to any consultation requirements. Coinbase prides itself on talent density. Our employees are among the most talented people in the world, and I have no doubt that your skills and experience will be highly sought after as you pursue your next chapters. How we move forward To the team that is staying, I know this is a difficult day. We’re saying goodbye to colleagues and friends you've been in the trenches with. But here’s what I want you to know as we move forward together: Over the past 13 years, we have weathered four crypto winters, gone public, and built the most trusted platform in our industry. We’ve made it this far by making hard decisions and by always staying focused on our mission. This time will be no different – nothing has changed about the long term outlook of our company or industry. And most importantly, our mission has never been more important for the world. Increasing economic freedom requires a new financial system, and we’re building it. The Coinbase that emerges from this will be more capable than ever to achieve our mission. Brian

We see our home planet as a whole, lit up in spectacular blues and browns. A green aurora even lights up the atmosphere. That's us, together, watching as our astronauts make their journey to the Moon.

AI is simply another tool in the toolbox. In order to be effective, engineers need a stable platform for change management and are expected to own the code they produce. I shared most of these thoughts in the attached post @brian_armstrong shared. We're excited to see engineers embrace AI in all parts of their daily workflow, and we're moving faster + safer than ever now thanks to this cultural shift 🚀

Hey, I made this chart and this is what my team has been working on the last year. Happy to share more thoughts about our strategy beyond LOC. While this is a super-simple metric to understand, it's not the only measure. Turns out AI also causes a lot of devx pain 🧵
Brian Armstrong@brian_armstrong

~40% of daily code written at Coinbase is AI-generated. I want to get it to >50% by October. Obviously it needs to be reviewed and understood, and not all areas of the business can use AI-generated code. But we should be using it responsibly as much as we possibly can.

@Andrei_Calazans and make sure that second argument is a lightweight compare, because in most cases it will be a noop and in other cases it needs to handle complex values

Doing FPS comparison on frequently updating UIs. Surprisingly using memo does not mean > FPS. The default second argument of "memo" is the same thing as React's prop diffing - a shallow comparison check. Don't use memo without a specialized second argument function.

We're looking for designers/cartographers/design engineers on my team to work on map-related experiences across @DesigningUber. Ofc I'm biased but we design the most interesting experiences that intersects with the physical and digital world :) DM’s are open 📫

React Compiler explained in 1 tweet: 1. It works on every platform that you can run React on 2. It enables you to completely forget about reactivity, and memoizes much more granularly than is possible by hand 3. No new APIs to learn, no rewrites, and incrementally adoptable

Shoutouts to the small group of engineers on my team who pulled this migration off AT SCALE 💪 If this type of work sounds interesting let me know! The App Infra team at Coinbase focuses entirely on Web + Mobile platform, tooling, and enabling quality UX 🪄
