LLMs are not the "stupid bit in the middle." They're almost the entire value. LLMs were wildly useful before any sort of scaffolding. They are not "dumb as bricks". They are highly capable, flexible, intelligent prediction machines.

The only one confused here is you, and you've still not managed to tell us in an actionable way how exactly CPU scaffolding is relevant here. Tell us, if it's so easy, or make your millions selling it. We're all waiting.

I'll give you a hint. CPUs never had to interpret the meaning of arbitrary content in order to do their job, and LLMs do.
