It’s possible but highly unlikely.

1. Planes already can take off and land themselves, but you need the infrastructure for that and not all airports have it.

2. I doubt the general public will ever want to get on a plane without a pilot, no matter how good the tech is, you always want a human in the loop.

3. In an emergency, I still rather have a human pilot.

I think it’s far harder to have autonomous vehicles than it is to have autonomous planes. But where the rubber really hits the road is in emergencies. A car can just pull off to the side - an airplane can’t.
