The boundaries between designer, engineer, and PM aren't about skill — they're about what each role can't do. AI tools are dissolving those walls. What's left is one thing: builder.
A role isn't defined by what someone can do. It's defined by what they can't. The wall between disciplines is the job description itself.
A button isn't a rectangle. It's two completely different abstractions of the same thing — with no shared grammar between them.

It's now as cheap to make the thing as it is to argue about a picture of it. The expensive part has moved.
Building isn't one mode. It's a spectrum you bounce between constantly. Knowing which mode you're in tells you what to optimize for.
The pixels aren't defensible. The Figma file isn't defensible. What no model can replicate is what lasts.
