Human body, esp. brain (or more broadly even nature) has a motivation to do more with less energy expenditure.
Drugs allows you to cope with hard things or allows you to escape the toll you have to pay.
Similarly, AI allows brain to do more with less energy expenditure. This is why it looks so tasty and is very addictive.
Your brain doesn't work at that hard, AI allows this, however there's no free lunch on that planet. The effort you give into something returns as quality and finesse, however it's tiring as well.
Addiction is a complex is a hard problem regardless what you are addicted to, it's not a light or easy matter to discuss, though.
OK, but not only that. People learn quickly that in most contexts, expending effort to create a high quality work is not noticed much less rewarded.
It's like anything goes in most human endeavors. Society is winging it; duct-taped solutions abound. Most people lack taste or a keen eye for quality, and only notice when there is something seriously wrong. Even then, politics and all sorts of other concerns skews how people respond to things. This is why we complain about AI slop in the fields we know about, while the public at large think AI is the best thing after sliced bread.
Faced with this, unless someone is really passionate about their work, they eventually kind of tune out, and then look for how to expend the least effort possible to get whatever (uncertain or politicized) reward they can in their endeavors.
