Exactly this. Everything I've seen online is generally "I had a problem that could be solved in a few dozen lines of code and I asked the AI do it for me and it worked great!"

But what they asked the AI to do is something people have done a hundred times over, on existing platform tech, and will likely have little to no capability to solve problems that come up 5-10 years from now.

The reason AI is so good at coding right now is due to the 2nd Dot Com tech bubble that occurred between the simultaneous release of mobile platforms and the massive expansion of cloud technology. But now that the platforms that existed during that time will no longer exist, because it's no longer profitable to put something out there--the AI platforms will be less and less relevant.

Sure, sites like reddit will probably still exist where people will begin to ask more and more information that the AI can't help with, and subsequently the AI will train off of that information; but the rate of that information is going to go down dramatically.

In short, at some point the AI models will be worthless and I suspect that'll be whenever the next big "tech revolution" happens.
