Exploratory yes but when you're still exploring it's not a great idea to bet a whole company on something that might not pan out. Or to dump stuff on users with lots of promotion that may or not be actually useful.

And yeah for accessibiity a lot of this is hugely useful but that's a very niche usecase.

And yes AI-assisted search (or deep research, even better) is also something I like. But it's also because search engines themselves have become so enshittified and promote bad content first.
