It's not just "usage without discernment", it's that AI flattens some costs which are very obvious and very measurable (coding) in such a way that it introduces or amplifies other costs which are much more diffused and hard to measure (code and design reviewing, bug fixing, maintenance, adding new requirements), plus AI is totally incapable of doing the higher level tasks that shape what code needs to be done (technical analysis, requirements analysis and in bigger companies technical architecture).
People who are non-experts, aren't really senior domain experts or have some kinds of unbalanced expertise (they've never really progressed beyond being a coder, or they don't have full life-cycle experience with big projects or they're in an industry or position where they just make the code, shove it out the door and it's not their problem anymore) just look at the one thing they in their ignorance think is THE cost in programming - coding - and go "hey, this AI thing is amazing" even while AI is creating all sorts of much more time consuming problems which they don't really understand formally (they think those things are just "bad luck", "there's nothing we can do about avoiding this" and "it's just the way things are in programming") that require the time of people with higher expertise levels (i.e. who are more costly) to solve and AI doesn't even help with the kind of stuff which if done wrongly or not at all can condemn a software project to fail before it even starts like just half-way decent Technical and Requirements Analysis.
That's why you get some programmers going "this AI shit is amazing" whilst the really senior software development types are just nodding their heads and thinking "these people are ignorant as fuck juniors".
When I went to live in Amsterdam (The Netherlands) as an immigrant from Portugal I actually picked up the version of the Dutch "good morning" ("goedemorgen") from the south of the country even though I was living in Amsterdam (totally opposite side of the country) because some colleagues in the first company I worked in and were I started to learn Dutch, said it like that (it was pretty much the first Dutch word I learned).
After a while there learning the language and Dutch customs I eventually figured out I was saying good morning with basically a farmer accent from the south, by I just kept doing if for fun plus by then I abused the shit out of what I called the "foreigner excuse" (you can have tons of fun knowingly humouristically "misunderstanding" local expressions and "misusing" their language and if the joke falls flat get away with it because the locals hear your accent and think "just a foreigner, doesn't know our language well").
