Computers solve a lot of problems, as long as those problems are digital by nature. So naturally taking over an amateur mathematician who made his living as a computor, that was an obvious one. And we've gone through a cultural transition to solving all our problems digitally: using the internet to get all of our information, listening to digital music that is in a way a nostalgia of what the real sound was like, even trying to get machines to do 100% of our driving.
Blue collar? No, it doesn't work digitally, a huge amount of a blue collar worker's knowledge is not in his skull, but in his hands. Computers are remarkably bad at solving analog problems, just witness how terrible online dating is, it sucks. Or online classes, a totally inferior substitute.
