Sounds like just a replacement for Google assistant. I'm not excited about this at all, but short of latency issues, I'm not sure that it would be any worse than assistant. I've never found assistant to be very good and gets hung up on a requirement for very specific command phrases.
Gemini a no go for me just for the simple fact you need to unlock your phone to get a response. At the point I'm lifting my phone it's easier to just do whatever myself.
