The title is long enough so you look for more here? ;) This one is largely, in truth about energy and what it can do for us. Across the almost 90 minutes I cover how the concepts in the title logically cohere and depend one upon the other and we take a look at "the universal constructor" and compare the possibilities for an optimistic distant future with the reality of our situation now. Fair warning: many Australian examples are employed here. A tiny bit of Trump, a dashing of Deutsch, a yard of Yaron, morsels of Musk, some of Australia's mining magnates for better or worse and plenty of physics, philosophy and even politics. Those on my livestream may have heard a less polished (more profanity stricken) version of some of this material. This is me back to being polite even if there are reasons for frustration...   (See Youtube version for graphs, data and so on: https://youtu.be/ovs18b10d4Q )
