Even with voice-only stuff, isn't asking "Delhi weather forecast" much simpler than asking "Do I need an umbrella in Delhi today?". This doesn't sound right to me. Even if people are using the longer form that may be because of initial barrier and lack of training. Once they realize that they can get quality and accurate search results just by speaking keywords, they will switch to using keywords.

It's not only simpler, it's also more reliable. If I ask Google Assistant about the weather in the afternoon and it's 60F, it tells me the weather is great. But that's not the whole picture because if it's 60F now, it may be 50F or 45F in just a few hours. In which case, even though 60F fits some people's (not my) idea of great weather, I need to take a jacket and/or sweater with me when I walk out the door.

Point being, the AI doesn't know why I'm asking. It could make some reasonable guesses, but currently it doesn't even do that.

I could deal with that by learning the whole landscape of that it guesses about my question, when it's smart and anticipates my needs and when it doesn't, when I can and can't rely on it to do the right thing magically. Or I could just learn how to ask the question the way it needs me to, and that is a lot less to learn and worry about.
