Yes at the other end of the range, there was mention yesterday in the Party summer school on Technology of “smart fridges” which automatically re-order what you usually use when stocks run down:

That can be useful in socialism too. In fact I assume that supermarkets already operate with such a stock control app. That shows that socialism can work too without money or price of course judt physical amounts. If stocks run low a “smart distribution centre” will automatically order more.
What are we waiting for ?
