I think the only way you get there is if you assume _all state education spending worldwide_ goes to our friends the magic robots. That’d be a hell of a dystopia; idiocracy made real.

Who is going to create the content to train AI past 2025? If I don't have a job in 3d, I'm not posting to my 3d tools blog. If I can't sell classes on 3d tools, I'm not posting to my 3d tools blog nor creating classes for 3d tools. In fact, if I'm working a home depot job, a second part time hours job, and driving uber, all so I can try to live, I'm not posting ANYTHING useful. I'm too busy trying to survive. The 'posting useful/insightful things' in my spare time ecosystem requires a social class with the hours/energy/desire to do that.

Education has a shelf life. AI needs the pre-AI world in order for AI to train and be useful, but AI also wants to replace the pre-AI world with a new AI world. So the world will need to freeze in place between the two.

AI in an entropy machine.

Only if you can replace it completely, the total value of education material aggregators do not sum up to multi trillion and that is essentially what these replaces.

You can say it does a bit more than education material aggregators, but it doesn't do that much more, it doesn't replace paid education in any way so far.
