I don't want that though, and the majority of Europeans don't either. Delivery robots work in the US as a crutch for the bad infrastructure, whereas here in Europe, I can walk or cycle to the store. I don't need to do big, weekly shopping like Americans tend to do (I've lived in the US also!) because the stores are nowhere near as giant. We already have cashier-less systems in the form of self-checkout tills and handheld self-scanning. We don't need Instacart because the chains themselves handle the delivery.
Surprisingly, a lot of large companies use Rust in-house. I work at Nando's, one of our biggest systems is in Rust, and we're a chicken restaurant business, so it's not just limited to bleeding-edge SV companies.
Hoping we can open-source some of this stuff in the near future too to kind of show the world that Rust is ready.
