I think the dates you mention are going to turn out to be early. That said, I found college worth it, even when not strictly considering future employment prospects.

• I'm far more well-rounded after college. I had little interest in literature, religion, sociology, etc. when I entered college. While I certainly could have learned about these topics on my own, I probably wouldn't have. Having a more diverse education has also helped me be a better learner.
• Networking and other opportunities are easier when you are a student. I got access to two undergraduate research experiences, a scholarship, and an internship basically by showing up to things I wouldn't have known about if I had been teaching myself topics at home. One, I got literally just by talking to an invited speaker after a talk. Without these experiences, my ability to get hands-on learning in my field would have been diminished significantly.
• College was especially worth it for me socially. My closest friends today are some of my first year dormmates and people I've met through them.

I think if you're a super-motivated, well-networked high school student (e.g. someone who would get a Thiel Fellowship), or someone who knows exactly what they want to do, and how to get there, you can probably skip college. If you have any doubt, would benefit from a more structured learning environment, etc., you should at least try college. If AGI concerns you with regards to employability, try to orient yourself towards something where a significant portion of the work is non-routine.
