The application of blockchain combined with AI is not about sci-fi scenarios; there's a perfectly normal one:

You see a video where the main character is wearing really nice clothes, so you screenshot it and ask your AI assistant to help you buy that outfit.
The AI searches and lists places where you can buy it, one of which requires credit card payment. Would you give your credit card information to the AI then? Probably not, right?
But your AI can generate a wallet address with very low gas fees, like a SOL address, and tell you that you only need to transfer 28.9 USDT to this address. It will then connect to an AI-powered virtual credit card issuance node to generate a one-time virtual payment card, which you can use to buy the clothes you want.
This business is huge, comparable to Tether's stablecoin operation in 2017.
Based on current shopping logic, would you dare to give the AI an Alipay payment API? Would you dare to give it your credit card? But you would definitely transfer funds to the generated address, because if the purchase fails, the AI can either refund you or the generated mnemonic phrase is stored on your computer.
As for AI combined with blockchain to do market making, as long as you're willing to be the first mover, you can definitely make money. Of course, there will be trial-and-error costs, but that has nothing to do with ordinary people.
