That's not how fads work, however.
The Degenerative AI craze started because barely-capable software was hyped as the Next Big Thing and then failed to deliver. This has happened before in AI. At least twice. The old failed technologies still exist. They're vastly improved over the versions that caused their "winters" (as their utter failure was termed). Nobody has rallied back to them. The same will happen with Degenerative AI.
The problem, of course, is that there is no agreed-upon definition of what "Intelligence" even is. This seems to me to be a critical failure of people wanting to make an artificial version of it. "We've made Artificial Geflugenschurz!" "What's Geflugenschurz?" "That's not important. What's important is that we've made the artificial version of it!"
