I swear, whenever I try to use it, it just makes me wish I could delete it. I ask the answer to a simple question and it gives me a whole essay on how this one aspect of what I said is more nuanced than one would imagine, and I'm left there waiting 5 minutes to get it to say anything of substance, but it doesn't when I explicitly tell it to "just give me the fucking answer", which I have to say every time for it to say anything useful.
It also doesn't work with timers or anything actually useful and I doubt it'll get any better with third party app access.
Google assistant was so much better, it even still works with its servers being down (for me at least) because it's a better assistant than whatever Gemini is supposed to be.
