Well no. Micropayments imply you pay authors. Adsense and other platforms do not require that. Apples and oranges, fyi.

Micropayments are suffering because most folks aren't willing to pay for content. Paywalls have shown that depending on the few is a viable strategy.

You say that an ad supported web needs to die, but I will point out that such a move would even kill Wikipedia, as they rely on their ad-driven donations to keep them alive.
