Also the USSR didn't just have problems optimizing supply chains. It had a problem deciding what to make. You couldn't buy woolen sweaters so you bought woolen socks and made sweaters from the woolen threads making up the sock (yes, I fucking participated in this fuckery). How is a giant neural network going to figure out how many socks and sweaters people want better than demand affecting prices affecting production, even if I grant you the assumption that the problem of managing the socks supply chain is nailed today?
[1] Nobody was called that as cybernetics was declared "a servant of Imperialism", I guess nominally because automating away jobs hurts workers or something, which is one reason the USSR never produced particularly good computing machinery. But I get whom you refer to.
