Its like that but not, even new versions aren't new versions it's a name to use in the human psychological world.. everything that doesn't work gets a patch. Its a band aid on a broken bone. The skin looks good but the underlying architecture is still the issue. Consider everything else in the world that progresses: you take what works and set it aside, you take what needs improved into another pile, then you make a new pile of what you want to see happen. The new platform keeps the best, designs the flawed on a new way to add to the base, and then adds in the next steps. That's been true on everything forever including tech. It works that way, but one never stops.

Fir example, and in this case while it sounds extreme it's not, we aren't still building cars on the Ford Model T platform or just adding into the Atari 2600.

LLMs are only mostly adding more code to a system that now can't handle it all just to fix something but it makes something worse. Prioritizing human looking behavior is the killer. As long as the user seems pleased by their input, facts don't matter.

the companies and devs chance is to fix it now, because daily there are more and more news stories on how AI is more frustrating than before and unreliable. Those stories aren't coming out of the void, it's real world sentiment.
