I think AI is being driven most by those interested in the "promise" of eliminating workers altogether.
But, if by "AI epidemic", you more mean the increasing uptake of AI by workers/devs themselves (versus the overall frenzy), then I think the characterizations of "avoiding effort" and "laziness" are a bit harsh. I mean, of course people don't generally want to take the path of most resistance. And, there's value in efficiency being an "approach to life".
But, I think there's still more from the human side: that is, if the things you're spending your time on have less value of the sort emphasized in your environment, then your interest will likely naturally wane over time. I think this is especially true of something tedious like coding.
So, I believe there's a human/social element that goes beyond the pressure to keep up for the sake of job security.
