Google teamed up with five retailers to launch the UCP protocol, providing standardized APIs that enable AI to help you choose and place orders for products. Amazon isn't included here, possibly because A has its own AI solution. For now, this protocol only involves five companies, but I believe the ultimate goal is for most businesses to integrate with this API. This way, the middleman can be completely eliminated, and AI can directly connect with manufacturers to buy the cheapest products. Musk commented on this tweet.
