AI isn’t just a “machine”, that’s just a naive way of thinking about it. That’s such an industrial Era lens you’re looking at it from.
Seriously, I don’t care how “complex” you think your job is or how much “problem-solving” you think you can do, give it a bit more time and an AI will be made that is capable of not only replacing you, but learning and self improving at a rate faster than you’ll ever comprehend.
