Ask HN: What do you wish digital assistants (Siri, Alexa, etc.) could do?

I mostly use Allo/Google Now but I've spent time playing with Cortana and Siri as well. Some random things I wish they could do include: Tell me when the high/low tides will be. Do things at a later time (tomorrow at 5 message Jack to bring the frisbee) Of course we'd all like a good API to make our own stuff.

What would you want the assistants to do that would make them more helpful?
