Look, I know this might not be a popular view here on HN, but I think this is useless. And bad. I'm not talking about the technology behind it (I think it's an amazing achievement).. I live in Barcelona and I have at least 5 medium-sized supermarkets within 5 minutes walking distance from my home. Plus there are several smaller shops that sell fruits and vegetables. I know all the people who work in these supermarket…
Technology like this will make a lot of jobs obsolete. And, in the short-term, there will be a lot of problems with unemployment or underemployment. But, ultimately, a system of universal basic income (or something like it) will be implemented, allowing people to disassociate their identities with their jobs. It will free up their time to do other things, like help out in their communities, create art, or pursue their other passions. They can still work if they want to, but they won't need to. And they'll be able to choose jobs that they're passionate about instead of the jobs they have to do to pay rent and provide food.
Stores like this won't remove the interactions you have with your neighbors - those interactions will just change locations. Instead of seeing the cashier at the supermarket, maybe she'll be giving your daughter singing lessons because she was allowed to focus on something she loved doing instead of something that paid the bills.
