Okay ill tell you. You need to start a startup that sets up a good number of cameras at manual labor jobs. Most of the footage will be completely useless but every day you hit a once in a day event, every week you get a once in a week event, every month, every year, every decade etc! Then the guy working there for 40 years wacks pipe 224 with a hammer 50 cm from the outlet and production resumes.
The footage can be aggressively pruned to fit on the disk.
When the robot is delivered in 2033 it can easily figure out, from the footage, all these weird and rare edge cases.
The difference will be like that between a competent but new employee and someone with 10 years of experience.
I can see the Tesla bots disassembling the production line already. Or do you think it wont happen?
