Ah if you look at it from the perspective of doing research or other deep intellectual work by 22, I can see your point. Certainly if that is the peak of human mental capability (not something I can argue for or against but I'll take it as true) you ideally would pursue a focused education up to that point that allows you to dive deep into a challenging problem. IMO this is different from wisdom however, and in fact pursuing the variety of experiences and interactions with others that you need to build wisdom will distract from the focus on your research subject.

I'm not saying go into the cave and toil. You would still do all the stuff you do socially. Just your academic and professional subject matter would be tailored like it is when you reach undergrad and drop certain subjects in favor of your specialty. You still socialize a ton as a researcher in undergrad and grad school and beyond. Research is very much a collaborative effort too, unlike a lot of jobs or academic learning up to that point. That being said I don't think some magic threshold is reached with that when you reach 32 vs 22. Some people famously lack any social skills all their life. Some people are socialable straight out of the womb. This isn't a linear process.
