It seems clear that the founder's record has some significant failures, but thinking the other way, are there other founders who've been successful today after similarly significant past failures? "Past performance isn't indicative of future results" or however it goes. It's easy to get stuck judging people based on their history, so you easily skip over other details that might make their current efforts different, we all think (hope?) we grow, meaning so does this founder, despite past failures. I'm not trying to say that this is a signal either way, but I wish others don't judge me in the same basic way in the future, as I too have failed in the past (although not about solving nuclear fusion) but think I'm getting better every day. Of course, people will judge me and others either way, but it seems more reasonable to not not just jump into history first, and focus on other details that actually evaluate the ideas themselves.
