Micropayments introduced too much friction for you, a human. You have to think about how much the thing is worth, and consider whether the merchant is trustworthy, and enter your details to perform the transaction. Maybe you’re unsatisfied and want a refund.

Say it costs 1.7 cents and delivers 3.2 cents of “value”, you need to be able to do all that work in less than 1.5 cents worth of your time. You can’t do that as a human. But an agent maybe could, to pay for content or MCP calls. I see a big role for micropayments in this genetic future.
