I mostly have experience with Bing. And it's because they keep forcing their shitty AI search splash page on me every time I want to do a normal web search. I turned it off in the Edge browser but what do you know, it keeps coming back.
Any new feature a company repeatedly forces on me is going to be starting from a hole it has to dig out of. The bigger the corporation, the more immediately resistant I will be to it. "ChatGPT" and "AI" as the latest buzzphrases grate on me.
Outside the big corporations, I'm keen to tinker around with it some. I've done some machine learning stuff in years past, but this a large step change in what is available to hobbyists.
