I appreciate Ritwik's concern but fully agree with Eric's analysis. Bitcoin is energy intensive at present but already much less so than gold. New digital coins based on more energy efficient algorithms will surely emerge as the competitive pressure for decentralized finance grows. We all need to better understand the accelerating efficiencies and economics of decentralized finance and economic densification and dematerialization ("D&D"). We also must remember Kryder's law, which observes that the energy required per computation is halved every two years. Computation, not physical extraction, is at the heart of the future of human experience and value creation.
