My question is what happens when you veer off the happy path for a given task? Like if your hotel cancels, or thinks you didn't pay and you did? Seems like disasters waiting to happen.
I wouldn't even trust that it had booked the hotel on the correct date, or with my breakfast or room preferences. I'd need to go double check everything it did anyway, so what's the point.
To be fair - I work with humans who I feel the same way about. We will be able to use these devices when we've seen they work over and over. Trust is only ever earned.
The accuracy problems will eventually be solved. The point is to remove you from the decision making process of spending your money and delegate that to the institutions who want your money. Sure, the itinerary looks good, but since you haven't actually planned it yourself you don't know what the tradeoffs are. This is the end-goal of capitalism, extract the most value from people and resources as possible, and launder all of the anti-competitive and scam-adjacent behaviors through "the algorithm!" Just like how the police launder racist policies through statistics and terrible facial recognition or predictive policing software.
