In my experience the differences are mostly between the chair and the keyboard.

I asked Codex to scrape a bunch of restaurant guides I like, and make me an iPhone app which shows those restaurants on a map color coded based on if they're open, closed or closing/opening soon.

I'd never built an iOS app before, but it took me less than 10 minutes of screen time to get this pushed onto my phone.

The app works, does exactly what I want it to do and meaningfully improves my life on a daily basis.

The "AI can't build anything useful" crowd consists entirely of fools and liars.
