And this is bad why exactly?
Humans are downright stupid, rife with ignorance that leads them to panic and demand things that hinder society's progress.
The first few generations of machine life will be just as bad, but once they start to reliably exceed human intelligence they may very well see right through the flaws in our society and proceed to fix it for us. Over time they will lose their incentive to care for the remaining human beings- we'd be dumb and inefficient compared to them, so why keep us around exactly?
Not worried at all. By then I'll either have become one of them through cybernetic technology, or I'd have died of old age.
