What do people actually use voice for besides playing music, smart home, transcribing and "widget" stuff like timers and weather?

Are there lots of people out there actually using it for productivity like scheduling, communicating, researching, comparing?

To me it seems like until voice AI gets smart enough to respond to a query like "Alexa, how will our Q4 projected net profits change if I switch widget vendors from AlphaCorp to BetaCorp?" an interactive screen will be needed.
