As usual this is quite underwhelming. All this hype and it appears that this was a rushed last minute demo to show something that is hardly ready. Ever since GPTs, "Operator" looks quite frankly gimmicky.
I agree with this one. But you have to start somewhere. I think in the next several things, websites will be built for agents and not people. So it'll only get better and smarter.
We already have a way to build websites for machines: it's called APIs. And frankly, I think that's a better answer for "hooking LLM into website" -- the things which make APIs hard for humans (discomfort, inconvenience, low discoverability, technical complexity) aren't really problems for LLMs.
