Better UX does not buy you a datacenter farm to train state of the art cutting edge models. Right now the only people who can do that are the technobility class.

It does not, but it might encourage more people to care. Worrying about training is a luxury when you are starting from a baseline of "OpenAI spies upon me and controls my access". Let's focus on getting every Tom, Dick and Harry 1) on board with LLMs, because they're happening, 2) habitually using local software.

The same used to be true of being able to program computers and compile software.

Of course the frontier will always be unattainable, but that's like pointing out that I couldn't buy my own Cray supercomputer.
