I don't know if it's obvious information or not but if you talk to random people in San Francisco the general thing they say is that software is commoditized cause so easy to make anything with AI fast (like how I cancelled all my SaaS subscriptions and just vibe coded a replacement for free) and that everyone smart is getting into hardware cause it's still difficult to enter, kinda related to the Midjourney Medical thing too

Four types of people at every company now

but also, people get 10x worse when they go from bottom left to top left

Demo Day is here! Four new products. One incredible cohort.

Our 2025 Engineering Residency Program devs have spent the last five months building and shipping real software in a “post-AI” world where speed, creativity, and grit matter more than ever.
Here’s what they’ve built: 🧵

One of the best ways to utilize AI is to be free to ask dumb questions; work shamelessly toward gaining _expertise_.

[Garry Tan @garrytan]

People playing startup house think “build a demo” or “get a first customer” is some sort of check mark in order to join a club or pass a test

Do you understand starting a company is do or die? Either your product is something people want or not. We want you to make a great demo or build something awesome not as check mark on the way to something.

Either you make it or you don’t. There is no other bar to hit. Those things we want you to do are literally the necessary steps it will take to win in a market.

Startups are pass/fail.

Cursor + Claude Sonnet 3.5 is good, but combine it with Vercel v0, and it becomes even more powerful. Now, you have both a backend and frontend end-to-end solution stack.
