What about autonomous drones then? They are not planes?

The real reason we have pilots in commerical jets is that they are a failsafe because a mistake in your automated system can kill 100+ people and guess what? It still does from time to time even with a human piloting the "beast."

It is not impossible to have fully automated planes. We just cannot afford to make any mistakes otherwise people will die so we keep pilots as failsafes.

Nobody will die if your claude code hallucinates.
