Yeah this is right. It's like being a software oncologist. Often there's nothing to do. The patient is somewhat ok, and intervening would mean risking death du

Yeah this is right. It's like being a software oncologist. Often there's nothing to do. The patient is somewhat ok, and intervening would mean risking death due to the tumour being near some critical blood vessel. At most you have some routine maintenance to do on a daily basis. Cut some things here and there, reroute a few small things, tell the patient they need this or that medicine. You might even find it interesting to learn how the body of code works, the journal of previous surgeons, the little nooks and crannies where interesting decisions are made. But you are never asked to rebuild the entire body.
