While Gemini is actually fun to talk to, it's also pretty pointless at this time. It can't do anything useful, like starting apps, taking notes or give you directions, unlike Google Assistant. I actually tried in my car and the result was abysmal, with some really weird infuriating responses. The worst one was its response to 'play music from [some band] on Spotify' 'I will now search for [some band] on Youtube Music' ... not only doesn't it have the ability to start Spotify (nor, as it turns out, youtube music), but it just ignore any other streaming service apart from Google's own.
Really disappointing.
