uBlock Origin seems to have ~15 million active users between Chrome and Firefox (source https://en.wikipedia.org/wiki/UBlock_Origin#uBlock_Origin). If it only spared us 10 seconds a day on average (probably a super conservative estimate), it would save the equivalent of an average human life (~70yrs) every 15 days! (And given that probably at least 70% of users don't use an ad blocker, it's infuriating to think what's the "human" cost of ads on the web alone...)
