I want the version of Google Assistant / Alexa / Siri that actually works. I'm possibly being uncharitable - the speech recognition is fine but to me they feel like talking to a mannequin, "there's nobody home" so to speak.

State of the art UX for this is still calendar and notes apps, want it to be Jarvis.
