OP is a robot who is desperately coming up with excuses to avoid being sent to the mines

I never said it couldn't be done. Just that it's really expensive and very complicated, (that's the whole looking ahead and reasoning the dangers - AI robots are not yet that capable), vs the cost of human life.

What IS being done is above ground human supervised robotics doing VERY simple tasks. Because that's all they can do right now. But it's an expensive buy in vs cheap human labor so you don't see it much.

As I said, none of you here get your hands that dirty with that type of work. You just complain from afar.

It can't be done by every company/can't be done en masse at an economically viable cost.

But it can, and is, done in smaller cases.

These things aren't mutually exclusive
