Comfortable man living in tech dystopia with all power over his own life removed and abstracted from him is a disaster the Unabomber claims and then his manifesto lays out exactly what to expect in the future.
I don't subscribe entirely to all his claims/views but he's currently w/a perfect score in way of predictions how mankind would progress under a future dytopia. Read his manifesto-thing sometime, though he's apparently expanded it into a bunch of books while in supermax prison.
tl;dr (remember this was written in the early 1990s) man will be unhappy and unruly, meaning doing terrorist /criminal shit that won't be tolerated by a future society. They will try and dose future man with drugs and send him to shrinks to 'be happy' and it won't work. They will try and breed out violent genes from man but it still won't work. Just read it yourself
