I say that as a Mac user with a ton of Apple stuff, so I appreciate that design is function, but every time a company tags a product with the word 'experience' it's a red flag.
Every way a company interfaces with customers is an experience. Is the standard Google Search not an experience? Do users of Google Docs not have an experience of it? The implication is that this time they considered design, as against with everything else. They might as well call it Search Generative Well Designed Thing. Presumably unlike the other stuff they do. Just make it all good. "This time we made it an experience". If you have to say that, it's implicitly assuming failure as the default. Just call it Google Generative Search, and make it actually good.
I know, sorry, too much of a rant.
