I would prefer to see 2 options in browsers:
1. LSAT[1] support for micropayments (recently mentioned on HN[2])
2. RandomX[3], mining XMR for the site owner
Both provide something useful, replacing advertising and/or subscriptions for the site owner, rather than solely wasting energy. Let's eliminate captchas and advertising together.
