I think these sort of people exist, but they are likely quite rare. I think it'd lack humility to claim I am one of those people, but I will say that I found several other people who were like me but more in this regard during my career by trying many different hobbies and identifying people I respect and work with that share these hobbies. The Gallup StrengthsFinder personality assessment has two strengths, "Learner" (breadth) and "Ideation" (depth), people who have both are rare and perhaps jokingly called "certified know-it-alls", but it's been my experience that this is pretty much true and some people do have the personality to pursue many varied disconnected interests at depth. It's also one reason I believe STEAM is a real thing, because I've met many folks like this that are as gifted in artistry as they are in (physical) engineering and mechanics, as they are in software development. I certainly lack the gifts in artistry myself. I don't think I've ever met anyone who has depth in every field of study, but I don't think this is a fair requirement to be considered a true generalist.
