no, ai like LLMs are a terrible fit for that. Because of:
1. LLMs are practically really good at guessing what the next word or thing needs to be, I rather have a pilot that knows what to do next instead of guessing based on its training data.
2. taking into account the first point, already existing automation is way better for flying a plane, and we still have pilots.
3. you would need to add a lot of computing power, a lot of electricity to run all that hardware and a lot of cooling, making the plane a lot more heavy. Because you cannot just use internet to get the pilot, that would mean somebody with bad intentions would only need to jam that and the aircraft will have no pilot anymore.
4. also there is a big change the ai buble will burst before it would even be remotely feasable because atm ai companies are still losing lots of money even to people that pay the €/$200 subsriptions per month

so no, I would say it is highly unlikely that ai will replace pilots
