That’s interesting if it’s actually true. I think it’s important to keep in mind that it’s also their own marketing materials…
Then again, Bill Gates thinks it may have plateaued. He ought to be privy to OpenAI's going-ons. That, and Gemini was underwhelming.
Gemini Ultra wasn't yet fully released, so I'd like to correct your statement to: Gemini will be underwhelming.
He didn't say AI may have plateaued. He said the OpenAI may have reached the limit of the current design. Very different thing. From your link below:
He anticipates a stagnation in development initially. The billionaire said that, with GPT-4, the company has reached a limit, and he does not feel that GPT-5 will be better than its predecessor.
In other words: 1) There's (a lot of) money to be made in making it better. 2) Releases are happening constantly, why would that stop? 3) Lots of recent research still that hasn't been productized and also that opens the door to future improvements.
