Mike Brock joins me for a conversation about the theory of knowledge, the role of social consensus in the meaning of words, where rights and ethics come from, the role of technology in moral sentiment, and how Bitcoin impacts the ability of the state to generate revenue. Mike Brock leads TBD at Block, which focuses on decentralized finance. Mike has held a number of leadership positions at Cash App and was responsible for setting up Spiral, an open source initiative focused on a more accessible global financial system for the internet.
