By the time you've specified your preferences specifically enough for the agent to do what you want, you may as well have done it yourself.
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.
yes, it's like using a company travel agent. doesn't save you any time really, once you have specified all your constraints.
Summoning Ubers arguably is a great use case because at airports you're probably busy moving to the pickup point and dealing with spotty signal on the way there. Comparing multiple services by hand in that environment is kind of a pain in the ass. It would be great to instead use an agent that is probably talking to their APIs to do this faster, and I can focus on other things at that moment like texting whoever I'm seeing.
