Iβve left Anthropic after more than a year of working on Claude Code and seeing it scale larger than I ever imagined.
I have really loved working at Ant and believe deeply in the mission, and most of all, the idea of a race to the top.
The idea that if we work hard and responsibly, we can raise the bar and inspire others to great outcomes. And if we all push each other to be better, things can be radically good. I will carry the spirit of this with me forever.
My colleagues at Anthropic are the most talented, thoughtful, competent, and earnest people I have ever met. I am glad they are at the wheel and trust them deeply.
To the community on X, thank you for everything. Youβve made this the most fun (and sometimes stressful) job Iβve ever had.
For me, it is time for a bit of a break before diving into something new.
If you want more excellent Claude Code content, you should follow @addyosmani , @lydiahallie, @_catwu, @ClaudeDevs and of course @bcherny who started it all.

1.5 years ago, I left my 9β5 job after 14 years in corporate.
Since then:
β 3 MVPs failed
β $0 monthly income
β ~$200/month tool costs
Still, the learning I gained and the audience I built are priceless.
Not there yet. Not going back.
Saving this tweet for the future.

You didn't waste time. You lived life. Too many people beat themselves up over missteps that were actually lessons. If you're reading this now, you can adjust. Give yourself some grace⦠you're human, and everyone has shortcomings!!
Most people start building a digital product with the wrong question:
βWhat can I create?β
A better question is:
βWhat painful problem can I solve for a very specific person?β
Dickie Bush's journey is a great example.
His first digital product was a collection of podcast summaries.
It made around $400.
His second product, Ship 30 for 30, eventually generated more than $2M.
The biggest difference wasn't better technology.
It was better positioning.
The framework is surprisingly simple:
1. Pick a category
Writing
2. Niche down
Internet Writing
3. Niche down again
Internet Writing for Beginners
Then identify:
10 Biggest Problems
β
10 Most Desirable Outcomes
β
Choose the most painful problem
β
Build the product around solving it
And there's one more important lesson:
Your product might solve 10 problems.
But your positioning should usually lead with one.
People don't buy information.
They buy progress toward an outcome they care about.
So before building another course, community, template, or SaaS product, ask:
Who exactly is this for?
What is their biggest problem?
What outcome are they willing to pay for?
The clearer those answers become, the easier product creation becomes.
What you measure determines what you improve.
But choosing the wrong metric can make a team extremely efficient at optimizing the wrong thing.
A few examples:
Hours worked β Productivity
Clicks β User satisfaction
Total users β Sustainable growth
Bugs fixed β Product quality
Average latency β Worst user experience
The lesson is simple:
Good metrics should be:
β’ Impactful β improving them actually matters
β’ Actionable β your team can influence them
β’ Responsive β changes appear quickly enough to learn
β’ Robust β they are not dominated by noise
But one core metric is not enough.
You also need instrumentation.
Core metrics tell you what is happening.
Supporting metrics and observability help explain why it is happening.
And there is one final requirement: data integrity.
Because bad data can be worse than no data at all β it gives you confidence in the wrong decision.
A useful engineering loop is:
Goal β Metric β Instrumentation β Change β Measure β Validate β Learn β Improve
Measurement is not just reporting.
It is part of how teams decide what to build next.
i wanted to build something this weekend that needed GPUs but wasn't sure where the cheapest place to host them was...
so of course instead of building the actual idea, i built gputable.dev
AI coding at scale isn't just a model problem. It's an engineering problem.
Uber recently shared how it is building what it calls a Software Factory, where AI agents operate across the software development lifecycle.
The scale is already significant:
β’ 3,600+ agent skills
β’ 30K+ skill executions per day
β’ Weekly AI users grew 7Γ
β’ Agent requests grew 9.4Γ
Yet AI spending has remained relatively stable.
The interesting part is how they achieved it.
Instead of simply searching for cheaper models, Uber decomposes AI cost into several variables:
Users Γ Sessions Γ Turns Γ Requests Γ Tokens Γ Token Price
Then they optimize each layer.
Some of the strongest ideas:
β Benchmark-driven model routing
β Cheaper models for specialized subagents
β Automatic context compaction
β Prompt caching based on session behavior
β Loading tools only when needed instead of injecting every MCP schema
β Running deterministic workflows in code instead of consuming additional LLM turns
β Grounding agents with a large internal Context Graph
β Giving engineers real-time visibility into AI cost
One example particularly stood out.
With proper context, an agent found the correct answer in 38 seconds.
Without that context, the same task took 20 minutes, spawned two subagents, encountered three errors, and still produced the wrong answer.
This highlights an important shift in AI engineering:
The next optimization frontier isn't only better models.
It's better systems around the models.
Model routing.
Context engineering.
Tool architecture.
Caching.
Evaluation.
Observability.
At scale, AI agents start looking less like coding assistants and more like infrastructure.
And that may be what the future software organization looks like:
Engineers don't just write software.
They operate a factory of agents that builds software.
Building mobile apps is becoming easier.
Building a mobile app business isn't.
AI coding tools have dramatically reduced the technical barrier to launching a product. What used to require a development team and months of work can increasingly be prototyped in days.
But that doesn't remove the difficulty.
It simply moves the competitive advantage somewhere else.
Today, the real game is:
Idea β Speed β Onboarding β Distribution β Retention
First, choose a problem people already care about.
Competition is not always a bad sign. If several apps in the same category are already generating meaningful revenue, that's evidence that customers are willing to pay.
Then build the smallest useful version.
You don't need 20 features.
You need:
β’ A strong onboarding
β’ A clear monetization model
β’ One valuable core loop
After that, onboarding becomes part of marketing.
The goal isn't simply to explain the app.
It's to move the user through:
Problem β Understanding β Value β Aha Moment β Paywall
And distribution should start before launch.
Study the content already working in your category. Test hooks, demos, creators and formats in volume.
But don't optimize for views.
Optimize for:
Views β Downloads β Trials β Paid Users β Retention
Finally, scale what survives the entire funnel.
Not every viral video deserves ad spend.
Not every feature deserves development time.
Not every user request deserves a roadmap item.
The strongest consumer apps increasingly look less like software projects and more like continuously optimized growth systems.
AI has made building faster.
The advantage now belongs to founders who can learn faster.
βHuman in the loopβ sounds like a solution to AI risk.
But having a human approve an AI agent's actions does not necessarily mean we have meaningful human oversight.
A recent paper from researchers at Hugging Face and Data & Society highlights an important paradox:
Oversight can degrade the overseer.
As AI agents become more autonomous, humans move from actively performing work to monitoring plans, reviewing outputs, and clicking approval buttons.
Over time, this can create:
β’ Approval fatigue
β’ Automation bias
β’ Reduced situational awareness
β’ Overreliance on AI
β’ Domain skill atrophy
β’ Weaker critical thinking
And this creates an uncomfortable problem.
The moments when human judgment matters most are usually the rare, complex cases where automation fails.
But those are also the moments when humans may be least prepared to intervene after spending months delegating the work to AI.
So the future of AI safety may require more than better models.
We may also need better human-agent system design.
The paper proposes ideas such as:
Strategic friction β make users think before consequential actions.
Bounded autonomy β automate low-risk work while reserving human attention for high-risk decisions.
Behavioral monitoring β measure whether humans are actually reviewing rather than simply approving.
Skill maintenance β periodically perform tasks without AI.
Workload design β use breaks and rotation to prevent oversight fatigue.
The goal shouldn't simply be:
Human in the loop.
It should be:
Human capable of understanding, questioning, and overriding the loop.
As AI agents become more powerful, preserving human judgment may become just as important as improving machine intelligence.

AI-native services may not need to remove humans from the loop.
They may just need to remove the linear relationship between human labor and revenue.
A common thesis around AI services is:
Human judgement β AI automation β Full autonomy.
But there is another layer that is much harder to automate:
Accountability.
Think about aviation.
Autopilot can handle most of a normal flight, yet there is still a pilot in the cockpit.
Not because the pilot needs to manually fly every minute.
The pilot is there for the abnormal situation β and ultimately owns the outcome.
The same principle applies to high-stakes industries such as healthcare, finance, legal, compliance, and life sciences.
AI can increasingly perform the work.
But clients still want a qualified person or organization standing behind the result.
This creates an interesting AI-native services model:
Expert knowledge β Internal AI platform β Automated execution β Expert oversight β Feedback β Better agents β Less expert intervention.
The objective doesn't have to be:
Humans β 0
It can simply be:
Revenue grows much faster than expert labor.
And that changes the economics of professional services.
Instead of selling software alone, companies can combine:
AI scalability + Human accountability
Automate the repeatable work.
Let experts handle exceptions.
Turn every intervention into feedback.
And gradually build a service business that scales more like software.
Money is easier to understand when you stop seeing it as something to chase β and start seeing it as part of an exchange.
Imagine a local market 300 years ago.
A baker sells bread.
A farmer sells eggs.
A craftsperson sells clothes.
People create value, bring it to the market, talk to each other, exchange what they have, receive money, spend it, and continue the cycle.
The modern economy isn't that different.
The marketplace has simply moved online.
Today, instead of only trading physical goods, we trade:
β’ Knowledge
β’ Software
β’ Services
β’ Content
β’ Experiences
β’ Access
β’ Communities
The underlying loop remains surprisingly simple:
Create Value β Enter the Market β Exchange β Revenue β Reinvest β Create More Value
This also changes how I think about rejection.
If someone at a market doesn't buy your eggs, it doesn't automatically mean your eggs are bad.
Maybe they simply don't need eggs today.
The same applies to business.
One unanswered message doesn't mean your offer is bad.
One lost customer doesn't mean your product has no market.
One failed launch doesn't mean the idea is wrong.
A βnoβ is a data point β not a verdict.
I also like thinking about business in two modes:
π River Mode
Talk to customers. Publish. Sell. Network. Follow up. Negotiate. Collect feedback. Participate in the market.
ποΈ Build Mode
Improve your skills. Build the product. Create systems. Automate. Research. Strengthen the team.
Strong businesses continuously move between the two.
Build β Market β Learn β Improve β Market Again.
Because money rarely appears simply because something valuable exists.
Value has to enter the marketplace before an exchange can happen.
