Well, I've been building algorithms which explain _why_ something was surfaced, not just being a black box. Everything is controllable from data sources, ranking/filtering weights and a feedback mechanism to tweak this.

As for monetisation, I've thought about this a lot - and I don't think the time wasting is needed to create a good product. Google Search certainly isn't fueled by dopamine hits, and from an ads standpoint, our users are saying exactly what they want to see every morning.
