Unpopular opinion here, so prepare to downvote.

The guy unlocked one of the fundamental building blocks of life making the world a better place, but yet he's being crucified because he thinks something absurdly false and demonstrably wrong is true.

Yes, he's stupid and likely a horrible person, but nobody is a perfect saint, and everybody - including you, who believes themself to be a normal, rational person - will have some irrational, crazy, and absurd idea rattling around in your brain. But that doesn't make you a monster or a demon. It makes you a human.

What impact is he having today? He's not running for President. He's not actively performing research, he's an old retiree spouting nonsense like any old, grumpy grandpa with a soapbox would.

We can't expect everybody to be perfect and to conform to our ideals all the time. Everyone has faults, and we need to understand a person can be really good at something, while still possessing neuroses or bad habits that, while not commendable, do not relate to getting his/her job done and don't disqualify you from doing it.
