A, lot of people think I'm strange for advocating weightlifting for the aged, when it's of most benefit. It's one of the reasons (and quite possibly the main reason) why I'm getting about, and enjoying life more, than most in my age group.
As for being replaced, it's quite possibly why, outside of computing, science has been in the doldrums for decades. It used to be that scientist got there through their ability to think scientifically (which Autistics do far better than most) but now, even in this arena, how well you socialise, and who you know, are far more important factors.
Those now referred to as Natural Philosophers were dominantly Autistic, but now such are hard to find in this proffession. This is especially true in "autism research" which is dominated by clueless touchy-feely types, who start with the belief that their way of thinking is some kind of ideal, which the rest of us should aspire to! Hardly ideal for those who are studying children who think differently.
Note, I wrote children, not adults; these experts have shown they have no desire to encounter those of us who are worldywise enough to defend our way of thinking.
