Yes the computer tech we have right now will most likely never replace human thought but can be tasked to be better than humans at a chosen group of tasks.
However if quantum computing becomes a working tech (and there are claims of research labs building working quantum computer parts right now) then it is Kate-bar-the-door. Because the limitations our current computers have will be blown away it will be a bigger change than both the Industrial and Digital revolutions combined.
From what I've read one paper claims one fully realized quantum computer will have more computing power than all of the computers created to date. If just a fraction of that claim pans out ten years after that date we will not recognize our world.
And for me, it is not “if”, it is “when”.
The only thing that is impossible for man is time travel. And we may even find a way to do that in some form or another, different from actually going there.
