* In the example where Google asked about holiday hours -- they can now automate gathering information about businesses in bulk without having to rely on any APIs or user supplied info. Interesting thought experiment is Google validating their reviews/business listings by actually calling businesses and speaking to a real human.
* This is going to be fantastic for accessibility. Maybe I struggle to speak, and I want a reservation. I can have the machine do the irritating work, and focus on just having a nice meal or getting a service (like a haircut).
* Google can scale out your requests, one to N. For example, 'Make me a reservation at a 4 star restaurant next Friday.' Google can immediately initiate calls against 15 restaurants and let you pick from the successes, then automatically cancel the reservations for the places you did not choose.
