I don't think they're equating it, moreso saying that, on a technicality, it's already a computer that's always flying the plane, but that the AI and the flight control system are quite different.
It's a fair comment given that they'd just been talking about how the AI might control the plane - will it give inputs to the state machine or have direct control over all flight systems? One would strongly assume the inputs must be to the state machine. ..but oh boy wouldn't it be interesting to just hand it full systems control!
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.
