AI has been controlling robots for a few years now, and is already doing quite a bit of work for programmers. I'm not sure how much of it exists in airplanes, but they pretty much already run themselves.
AI is pretty good at replacing other forms of heavy computing and also at replacing humans. AI is as good as the best doctors at detecting some things.
While there are a lot of misconceptions, some of them are with people like you, who just don't realise how much AI is being used, or, as has been done repeatedly over the years, classify anything that already works as "not AI".
