Amazon has giant warehouses all over the country to deliver things to people quickly, sometimes within a couple of hours. What is an LLM going to do about that?

Amazon has a monopoly in the US, but elsewhere in the world, 3rd party sellers have their own infra. Even in the US, sellers that sell outside Amazon have 3PLs they use that aren't as fast as Amazon, but also don't take a 20% cut on every sale.
