People have been predicting micropayments replacing ads (with differing technology implementations) for decades at this point and it's never come to fruition, so is unlikely to be taken seriously now either.

Tying it to cryptocurrency just seems like it's even less likely to get your regular Joe to onboard to this scheme, so I can see why it's never gained wider interest.

The difference here is that humans aren't the ones using the stablecoins or micropayments. Agents are. Humans will interact with agents like they currently do.

Honestly, some form of digital credits work just as well here IMO (barring regulatory hurdles). No crypto necessary.
