That last perspective is the most important one. I've known a few genius-ish people, and I recently had a jarring experience where one of them who's a bit older and retired, but definitely not mentally ill or demented, had gone off the cliff of believing in all kinds of crazy alien/government conspiracy theories and started working on some free-energy device, etc.

At first I found it shocking that he was being so completely irrational about these things and had become a "true believer" in so much crazy so quickly. But eventually I made the connection. All the innovative stuff he did earlier in life was no different. Every great idea he came up with and pursued with dogged passion was something that everyone else around him thought was stupid and crazy at the time.

Basically he's always been "crazy" in this sense, it's just that sometimes that ability to suspend disbelief and rationality works out well and you invent something useful that nobody else would've tried, and sometimes (probably many times!) it doesn't. His brain hasn't changed how it works, it just happened to latch onto the wrong thing this time.

Linus Pauling was a bona fide genius; he won a Nobel for his pioneering research in to chemical bonds, made important contributions to our understanding of crystalline structures and various proteins, helped explain the the molecular genetic cause of sickle cell anemia, etc, etc. He was a giant of science and will always be remembered as such.

But he also spent the last thirty years of his career refining and attempting to popularize a model for the structure of the nucleus (the "close-packed spheron model") that never seems to have gained much acceptance. He spent even longer advocating for megavitamin therapy, which is now generally regarded as quackery, and went to his grave pushing the idea that large doses of vitamin C can help cure cancer, despite numerous studies failing to support this.

I'm not saying that Wolfram is exactly like Pauling (although his fascination with his own work on cellular automata certainly seems to share some similarities to Pauling's fascination with the spheron cluster model). But I can't help but wonder if Pauling's reputation would be different if he had had a blog.

He also put the equivalent of a scientific hit out on Shechtman for quasicrystals
