I dislike stablecoins because they legitimize their cousin coins and because (I think?) they have transaction fees that create the wrong incentives for providers. I'm not sure what the real benefit is over prepaid (policy-driven) fiat currency with (possibly-paid) transaction records.
I can see how selling to bots could become so profitable that no one bothers to present directly to humans, but I look forward to an ad-free, much more capable internet, where paywalls are more like a headwind than a wall.
