Agents seem like they might be helpful for high-friction tasks, with a lot of data. But summoning Ubers and ordering food aren't really that.
The whole point of agents for this kind of stuff is to not have to think about it so you can focus on something more important than a mobile app failing to compute its core function alongside the other nonsense it's doing. And no it doesn't screw up the address either, this isn't 2021 anymore.
This one is not law. That absolutely exists ... but airports demand money for taxis to join that line of customers and so these got more expensive and are never the cheap option.
The rideshare race to the bottom model of pricing has some bad aspects to it, but choice for the driver before accepting the trip is one positive.
What would be great would be a unified car ride app which accessed all vendors. The AI layer adds nothing, I would say detracts actually, and it would not be more popular. UI is just superior to chat in many, many applications.
I don't have any kind of agent set up to do that now, but to me that sounds like removed friction even if I use it just a few times a year.
I constantly use the Ask AI thing in Google maps to tell it a complex route involving biking and transit and needing to be at a certain place at a certain time. It hasn't messed up on me yet. I would much rather specify the question in natural language than type anything into a rule based UI. In fact I built a toy app years ago that handled a few of my most common queries with the Maps API and I still never used it because of the friction.
siri is horrific
