I just watched the video. It doesn't at all say what you claim it says. It doesn't even remotely claim that AI model capabilities have stopped improving exponentially. I'm not sure where you got that idea. Advancements aren't limited to making bigger LLMS. Imagine if you will that you have a brain that has never been trained ... a baby. Over time it first learns to recognize objects and gains object permanence, then it learns the alphabet, then words, then sentence structure. It eventually gets to the point where it has learned basic math skills. It gets exposed to more and more ideas and concepts, and *learns* more and more. It learns physics, biology, neurology, and gains other medical knowledge. The size of the brain doesn't increase, but it gets closer and closer to being an expert on all of these subjects. That, loosely speaking describes the difference between making a neural network bigger and increasing its capabilities. My explanation is a bit simplistic, but that isn't a bad thing. The idea is to get you off of this idea that there is a linear correlation to neural network size and the capabilities it has after learning over time. You can empirically prove this to yourself by having a conversation with OpenAI or Google models from 2024 and then with the latest releases running them locally on *your* hardware. The hardware is the same. It is no more capable. The *models* however, are worlds apart.
