As long as they don't all need 2 pilots. I'd really like to see self-driving planes, must be easier than self-driving cars surely? (And, yes, I would fly in one)
A plane has to find a way of landing safely first. I am not versed enough in aeronautics to even begin to understand how hard it is to reach human-level in mayday situations.
The issue I think is that airplane autopilots rely significantly on sensors which occasionally fail. That means self-flying planes must be able to cope with sensor failures which generally means falling back to visual cues. Self-driving cars that rely just on cameras (rather than LIDAR) are a point of debate regarding their feasibility. Planes that would have to rely on just cameras likely have the same issues.
I wouldn't, if it was made by Boeing. Just look at how badly they fucked up something as simple as their MCAS system, making it only use input from a single sensor. That kind of incompetence isn't going to yield a safe plane that flies by itself.
