But the reality of the matter is that for every Krapivin, there are thousands of other people who tried but did not. And more importantly, there are hundreds of others who did the work, gained the foundational knowledge, and THEN made a discovery that changed how we think about the world even if only a tiny bit. While it's not as romantic, it's the way reality works. Mostly.
It sounds like Krapivin is continuing his education. And hopefully his hard work will hone his brilliance and help him to make even more discoveries in the future.
