Loved the debate but I am with Brian. Status quo has not changed the world fast enough and the current foundation/charity model is weighed down by hubris beliefs that they are the only ones who know best how to implement durable and lasting change - but that is arguable since it is the people who live in the communities these organizations serve that actually have the answers. Partnership and collaboration have always yielded the best results. Collaboration with billionaires who have experience actually changing the world, assuming they are good at listening to the constituents they want to serve , that is where I will put my hope - on the big bold visionaries. Maybe they will fail sometimes but so do foundations and charities - but the old guard are just less transparent about measuring failure as it can lead to less funding. There is a place for everyone to work together.
