Interesting. It makes sense and to me remains one of the most promising use cases for blockchain technology. Just look at Brave browser. It is already successfully giving value back to the user, 70% of ad revenue in fact. I wonder if the "MID" Mr Lanier refers to, actually needs to be an organization as he proposes. Or could it simply be a piece of (blockchain based) software instead? Another interesting related project that flies under the radar is Datawallet. They've been building a solution for exactly this. You get an online ID and and choose what data gets shared and with whom. And you would get compensated for it. I believe famous venture capitalist Tim Draper even invested in it. I know there are other similar projects, but that's the one I'm most familiar with
