It works great. All those management middle men of thousands of delivery and taxi companies have been replaced with software. Razor thin margins are enough to keep the servers running and a small team of developers managing it - for the entire planet.

It's difficult for any company to abuse their position as they're easily repalcable. So the margins will get lower, and more of the money paid by the customer will go directly to the supplier. Efficiency incarnate.
