Tourist,
I don't want an intelligent aircraft.
I don't want emotions or artwork or joy.
I just want a machine that flys a plane.
Presumabely though, you still want a plane which is "safe". So what would make an autonomous plane safe? Is it speed/reliability or intelligence? One of these components has the edge, which one? Surely, safety cannot be met by just relying on a "machine that flys a plane"?
