Dashboards and visualizations that can be easily composed with a natural language interface... it makes a lot of sense. Especially when combined with alerting services and/or chatbot-esque interfaces for automating workflows.
"Okay, let's bring in 'Sales' to the rows card.
"Nah, I don't like that. Move 'Sales' to the columns card.
"Hmm, that doesn't work either. Put 'Sales' back to the rows card but add 'Profitability Indicator" to the details section.
"Crap. Still not working. Let's start over."
Imagine 10 analysts in a room all talking like this :)
If I'm speaking i have to finish the whole thought and deal with excluding all my "uuhms" and half thoughts. If I'm typing i can intellisense prompt for relevant things. Correlate Sales with _[Discounts, ...]. I think terse natural langage descriptions of data views are really useful aside from voice.
Incidentally nothing like trying to play around with this stuff to make you super self conscious about uuh how you speak.
