the barrier for getting Linux to work is too high right now for a very large part of the population
My elderly (late 80s) parents have Windows on their laptops and it would be impossible for them to use it without my regular intervention. I might as well take the plunge and set them up with Linux.
Except for the other 1% who are trained and equipped to violently suppress the 98%. And if for whatever reason they fail to do the job, the killer robots will do it instead.
