And there's no reason to believe that it is. I know there's been speculation about model collapse and limits of available training data. But there's also been advancements like training data efficiency and autonomous agents. Your response seems to ignore the massive amounts of progress we've seen in the space.
Also the computer, internet, and smart phone were based on decades of research and development. Doesn't mean they didn't take off and change everything.
The fact that you're saying AI hit walls in the past and now we're here, is a pretty good indication that progress is guaranteed.
