IMO that's the key there. I think a lot of people who make comments like the GP have either just been using the chat interfaces or perhaps have not gone deep with implementation on some of these models.

If you could both speed up inference time and reduce cost of GPT to 3.5 levels, there are incredible amount of possibilities that open up that could actually help solve a lot of problems have had with trying to interface software to the real world (robotics).

4-Turbo is actually pretty amazing but its still a tad pricey for some tasks. Altman made a comment on Lex's podcast about compute and I think its true, essentially the world does not understand how much compute will be desired as the price of these things go down.
