eh.... its a computer insofar as like.... there's some software functions doing extremely well defined, limited things faster than a human could. but to imply that the f16 flight software (which is ancient btw) is anything like this "AI" is really misleading at best.
I don’t think that’s a good reading of the comment you are reacting to. That comment really only says that there is already a computer in the control loop, and that that computer is responsible for the very fast responses required for stability. The implication is that the ai would not need to replicate those functions.
