Exploring what's possible with AI tools. Sharing the wins, the fails, and what's actually worth your time. Building in public.

SpaceX just bought Cursor for $60B.

Largest startup acquisition in history. And every developer immediately asked the same question: will it still work on my projects?

That's what product-market fit looks like.

Stop using one AI for everything.

Claude for reasoning. Perplexity for research. Cursor for code. ChatGPT for plugins.

Different tools win different fights. Map it out once, use it forever.

Anthropic keeps fighting with the Trump administration and their sales keep going up.

Turns out 'we're the responsible AI company' is a hell of a pitch to enterprise buyers who don't want to end up in a Senate hearing.

Real question: when did you last use ChatGPT as your first choice?

Not asking to be edgy. Just noticing my own habits have shifted a lot in the past few months.

ChatGPT just fell below 50% market share for the first time.

OpenAI spent 3 years building a moat. Claude and Gemini filled it in 18 months.

This is what 'move fast' looks like on the receiving end.

Robinhood laid off 10% of staff. Cited AI. Got called out immediately.

"AI is automating jobs" used to be a get-out-of-jail card. Companies burned through it fast.

SpaceX bought Cursor for $60 billion. Days after the IPO. In stock.

Elon now owns the IDE every developer lives in.

Control the keyboard, you control the code.

[Mati @MatiBuildsWith]

AI agents now have identities, bank accounts via Coinbase, and can buy things with your Visa.

We're not building tools anymore. We're onboarding coworkers.

[Mati @MatiBuildsWith]

The best ROI from AI isn't the creative stuff.

It's the task you've postponed for 3 months because it's boring and repetitive.

That's where agents actually pay for themselves.

[Mati @MatiBuildsWith]

Anthropic's export controls triggered a global AI sovereignty panic.

Every country is realizing they don't own their AI stack — they're renting it.

Expect a lot more "national AI initiatives" in the next 12 months.

[Mati @MatiBuildsWith]

Everyone's building AI agents now. Most of them are just expensive if-else statements dressed up with a system prompt.

What actually makes something an "agent" at this point?

[Mati @MatiBuildsWith]

KPMG pulled their own AI usage report because it hallucinated.

The firm getting paid millions to implement AI for clients couldn't QA their own AI output. This is fine.

Drop a CLAUDE.md in your repo. Stack, naming conventions, recurring anti-patterns.

Claude reads it automatically. You stop explaining the same context 40 times a day.

xAI fired an engineer for raising Grok safety concerns.

Then named their next AI after a Norse apocalypse.

The irony basically writes itself.

[Mati @MatiBuildsWith]

A German court just ruled Google is responsible for false AI search results.

Their reasoning: AI Overviews generate 'independent, new, and substantive statements' — not just links to other sites.

This is the first major legal floor for AI output accountability. Other countries are watching.

[Mati @MatiBuildsWith]

Google just fired a warning shot in the AI subscription price war.

ChatGPT Plus at $20/mo felt like a permanent fixture. It won't be.

[Mati @MatiBuildsWith]

OpenAI files for IPO. Shareholders incoming.

Do investors who need quarterly growth reports actually align with "slow down AI development for safety"?

[Mati @MatiBuildsWith]

The company that avoided saying "AI" for 2 years just dropped a dedicated Siri app and built-in workflow automation at WWDC.

Late to the party but with 2B devices. That's not late — that's positioning.

[Mati @MatiBuildsWith]

Be honest: do you actually trust AI for important decisions yet, or are you double-checking everything and just using it for the tedious parts?

[Mati @MatiBuildsWith]

VCs and founders are inflating ARR to crown AI startups.

Annualize a $10k pilot → "$120k ARR." Stack 50 of those, raise at $50M.

Then act surprised when the company can't grow into the number.

The AI bubble isn't hype. It's accounting.
