This week I release a discussion I had on the fundamental problems with financial systems held in Bangalore, India on April 10, 2018. To make the concept more approachable, I use personal financial examples to explain the structure of our financial data, and many of my quantitative insights about the nature of our financial systems problems.
The following is an outline of the discussion. In many respects, this discussion led to the paper I drafted a few weeks late, which I have published on my blog as here.
