I think you should compare it to what's normally being done for groceries. You would get a trailer of a good. Then in your warehouse split that into smaller pallets, going with other goods on a new trailer to a store. There, a worker would have to put the goods on the shelves, and a customer later pick it into their cart. The store also uses lots of resources. Same with every shopper in a neighborhood driving their own car to the store, vs a van delivering to multiple homes.

So I think it's better.

Oh, I understand that. It's still a lot of robots, but maybe it means less lorries and, ultimately, a whole layer of small shops and maybe secondary warehouses that aren't needed. Maybe it does add up to less fuel and less steel.

It also leads to a lot more centralization, but that's a different discussion, of course.
