The first steam engines were also written off as being less powerful than a horse. The first electric motors were written off as being less powerful than steam engines. So it goes. I think both of these views can be true at the same time: ChatGPT (or, LLMs really) are revolutionary and they won't revolutionize the world the way technologists/researchers say. Early adopters will use the technology and do amazing thing…
This is pretty much what I've seen. ChatGPT (that's 3.5, right? GPT3 was interesting but still pretty laughable) was a massive step forward, and incredibly exciting to witness and interact with. But it still does have limitations, especially if you try to separate hype (which comes from an ecosystem of people who have incentives to hype it) from reality.
