A cholecystectomy is removing a gall bladder...

So how crucial could a step be on the gall bladder after it was removed?

They're not removing healthy ones for transplants, it's something done on literal medical waste.

Finding a gall bladder during surgery seems far from an insurmountable task for AI.

It is incredibly difficult...

There is a shit ton of human variation, shits just crammed wherever and it all pretty much looks the same. We still beat AI by selecting traffic lights in a picture....

Analyzing a scan? Yeah, that's AI all day.

Real life? A human will keep winning for decades.
