Your first sentence would lead one to believe that you have some substantial evidence to demonstrate the ignorance and falsehood you identified. It's impressive that you are regurgitating the same formulaic-template set of cliches that boil down to "X is so complex bro, how can you even?".
Note that I never claimed aviation relies on AI right now, most of the Autopilot systems are deterministic automation systems, but the original point stands regardless.
Your claim was that "the autopilot does almost all the critical work", and that couldn't be further from the truth in any airliners you can buy today.
I didn't say that an autonomous airliner could never be built. With more technological progress it might become feasible at some point despite the immense complexity.
As someone studying for a pilot license, your take is literally ridiculous.
You should perhaps look at all the crashes where the autopilot stalled the aircraft on approach due to incorrect settings.
