That's what the robots are for.

I am not expecting the humanoid robots to meet the hype for a long long time*, but even boring industrial robots (CNC machines), even boring commercial robots (vending machines), even boring household robots (lawn roombas) have made incremental changes even though we don't yet have an AI good enough to be general purpose over them all.

* for power-envelope reasons alone there should be a ten year gap between "self driving car of quality X" and "humanoid robot which can get into normal car and drive it at quality X".
