Here's my conversation with David Kirtley (@dkirtley), a nuclear fusion engineer, all about the physics and engineering of nuclear fission, fusion, and the future of energy. David is leading a team that's working to build the world's first commercial fusion power plant by 2028. This was a super technical conversation and a fascinating one, for both the near-term and the long-term future of human civilization. It's here on X in full, and is up on YouTube, Spotify, and everywhere else. Links in comment.

Why is there no reference to the Triffin Dilemma when discussing Trump's tariffs? It explains why the U.S. is caught in a financial paradox, and how this trade war - if taken to its end - will cause us to lose our status as the world's reserve currency, a 🧵 #TriffinDilemma
