I had the opportunity to go to college at 10 and again at 13. I’m very glad I went instead to a math and science boarding school (IMSA) instead. The networking alone I was able to do there has been incredible for my adult life. Add on the ability to pursue independent research projects at a level equivalent to grad school and I was able to maximize my intellectual interests while still improving my personal skills and growth as a human being, not just an achievement machine.
If I had gone to uni and graduated with a PhD before 18 I know exactly how I would have ended up. With few friends, low career prospects, and extremely low odds of improving that situation.
