I think the prototype thing is absolutely true but breaks down like all prototypes at the level of collaborating, sharing and evolving while handling entropy throug simplicity UNLESS you know what you're doing or the agent steers you with very opinionated tooling customized to your context. I'm thinking about empowering people to be builders and less so a software developer who can make the right tradeoffs.

Empowering people to work Tracer bullet style after they've selected their prototype of choice and thrown it away might be a powerful pattern that actually gets us into a nice collaborative space.
