I wouldn't say he's much different or worse than certain BBS sysadmins I knew in the early 90s... just that I'd never want those guys to be endowed with enough money and hardware to wreak their vision on the world
Maybe I'm jaded, but I feel like a lot of them did for a moment. Gates, Jobs, Zuck, all got their days of glory and it's quickly that everyone realizes they're a giant misanthropic asshole. If the pot of gold at the end of Altman's quest turns out to be as big as what he's priced it at, then yes, he'll be one of history's most successful sociopaths. If not, he's just another in a long line.
Not only one of those types, I can think of at least another one that's (IMHO) far worse than Altman. You know, the one with the social network everyone used to use before he turned it into a cesspool of disinformation, the one with the alternate Wikipedia, the obsession with the letter X?
tl;dr - the roots of the authoritarian personality grow fertile in the desire to be free of 'the filth of others'. Altman seems like he'd go crazy if he didn't keep his machine spectacularly clean ..
