How did this bit-twiddler suddenly become an expert on public health? He’s a programmer FFS.
Not even that as much as he bought/stole tech and marketed it as his.
His programming skills did not make his company successful.
He bought DOS.
He was visionary in how he marketed it. That was what gave him his success.
He has lots of personal issues. Have not seen much coverage of his X wife. She knows what the reality of his personal problems are.
He isn't really one of those, either. He wasn't very good at it in the first place; but, he had great business sense. So, he hired good software people, purchased working software, and maybe stole the rest.
