I think it’s a general thing with highly capable persons in expert and highly intellectual domains that eventually you kinda figure out what Socrates actually meant with “All I know is that I know nothing”
I feel like that sentiment is easily reached by anyone who is curious and likes to learns, so a lot of people.
If one thinks a lot, likes to learn and, maybe more important, thinks about knowledge and learning things, that person will probably get there.
A certain educational background probably helps but is neither required nor sufficient, IMHO.
