Probably the RAG AIs of the future will use it to help generate their users’ software. The AIs themselves might as well use the simple conventionally posix-y stack that we’re all familiar with, because they won’t have any trouble remembering complex invocations. But I bet they also won’t need as deep a stack (why have framework on framework on frameworks if you are an AI and don’t mind boilerplate and tedium?), so they’ll need a source for what over-complicated code looks like.

It will all be written from scratch in binary.
