You've given an argument for more gifted education, not less.
The fundamental issue is that some kids learn faster than others, so that if you want gifted kids to be around other kids their own age while still being challenged, you need to draw from a large region and cluster them together in one place. The most gifted children will have to be the most clustered. If you needed to go to MIT to be challenged, that is because of a lack of gifted education.
Separately, I think we should be very skeptical of the idea that a good default path for kids is to spend most days surrounded by kids within 12 months of their age. This sort of schooling has only been widespread for roughly a century; for the vast majority of history kids grew up with a much broader range of ages around them. I agree that getting thrown into a college dorm at 13 might be very bad, but I find spending all day with other 13 year olds to also be very bad.
There are lots of stories of kids failing socially when they are not with kids with similar emotional intelligence. I know people who have skipped only two grades who are brilliant, but socially off.
It is likely to depend on the child and what they would do well in.
As a fairly clever and socially off person who wasn't allowed to do any kind of accelrated program, I want to ask how sure you the acceleration is the casual factor, rather than say some underlying biological thing?
There are also uncountable stories of people hating school and finding relief upon graduating, and this is plausibly because it's a bizarre environment composed almost exclusively of kids. Personally, if I was gifted enough to go to MIT at age 13, I'd much rather do that than go to a typical middle school, the OP's experience notwithstanding.
I did not have this experience; a commenter upthread did. I was very lucky and had the opportunity to go to a good middle school and highly accelerated high school (Thomas Jefferson HSST in Virginia). But, knowing what I know about normal middle/high schools and MIT dorms, I would have rather gone to the latter than the former if those were my options.
