Earlier quoted context omitted.
What do you expect to be better in 30 years? We have NOW insane computing power, cool stuff like insane size FPGAs and super fast GPUs. Mechanical parts work with fraction of micron accuracy. And yet we have millions of workers picking simple shaped objects manually every day around the world.
It's still cheaper to exploit human laborers to pick those simple objects. There will be a reckoning once capitalism runs out of people to exploit.
I don't see us running out of Indians, Chinese and Africans in the next 200 or so years at least.
