"... replacing American workers with people that quite frankly should not be in the United States of America to begin with"
A stupid, baseless, and xenophobic phrase from a VP who quite frankly should not be in charge of anything to begin with.
Vice President JD Vance breaks down the data:
"If you are working as an H-1B visa in the United States of America, youāre earning $20,000 less than an American citizen hired in the same position. If you were brought in by one of these foreign outsourcing firms, youāre making $48,000 less than an American citizen in a similar position. So Iām sure that everybody here understands the game that is being played. You bring in indentured servants from outside the country, you lay off American workers and, if youāre a corporation, you make a ton of money by under cutting the wages of American workers, replacing them with people who frankly shouldnāt be in the United States of America to begin with."

What a fun chat with my dear friends @nyghtowl and @Neurotic!

The day a join. Coincidence?

We did it again. Temporal just raised a $550M Series E round at a $12.55B valuation.

āThe primary feeling between not knowing and knowing is frustrationā
From the Bass Clarinet intensive Iām attending at the @SFConservMusic but applicable to many contexts.
Itās hard to imagine a justification for this other than āwe hate legal immigrants tooā

The new White House policy requiring green card applicants to apply from outside the US is a capricious attack on legal immigration. It will hurt families, leave us with fewer doctors, teachers and scientists, and hurt American competitiveness in AI.

We talk about #justforfunc, distributed systems, and the impact of AI

This article describes something Iāve been noticing and couldnāt pinpoint: the difference between using AI as a tool to think vs using it to avoid thinking
āThe key issue is calibration: knowing when AI is helping you think and when it is quietly doing the thinking for you.ā
Running @temporalio workers on @googlecloudās CloudRun and @awscloudās Lambda? Take my money!

Cloud Run Worker Pools are now GA on @googlecloud and a great way to run @temporalio serverless workers š
So cool to see Cloud Run continuously evolving

In this letter, the CEO of Coinbase talks about non-technical teams shipping production code. Honestly, I donāt think he knows what heās talking about.
Using AI agents makes it possible for teams who are not deeply technical in the syntax of a language to ship production code. But that team had better be very deeply technical in managing the structure and quality of the code that is produced.
What the agents give us is the ability to disengage from deep syntax. But they do not give us the ability to disengage from modular design and architecture. You still need to be deeply technical in those topics in order to produce good production quality code.
This is an email I sent earlier today to all employees at Coinbase:
Team,
Today Iāve 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, weāre 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, Iāve 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, weāre 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: Weāll be concentrating around AI-native talent who can manage fleets of agents to drive outsized impact. Weāll also be experimenting with reduced pod sizes, including āone person teamsā with engineers, designers, and product managers all in one role.
In short: AI is bringing a profound shift in how companies operate, and weāre 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 ā talented colleagues who have poured themselves into this company and our mission. To those of you who will be leaving: thank you. Youāve 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. Weāre saying goodbye to colleagues and friends you've been in the trenches with. But hereās 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. Weāve made it this far by making hard decisions and by always staying focused on our mission. This time will be no different ā 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 weāre building it.
The Coinbase that emerges from this will be more capable than ever to achieve our mission.
Brian
