A lot of companies are focusing on "AI chief of staff" using normal top-down, close-ended systems.

What about a system that solves that problem in an open-ended way?

It would allow the focus of the ecosystem to flow to the use cases people will want, so the system as a whole will solve it emergently.

With all the iteration in userland, you don't have to structure any part too closely.

See what people, even early adopters, choose to build on from what others created: those are the load-bearing things.

The use cases can emerge, like a folksonomy.
