In this episode I take a long view from the ancient history of Greek Gods through to David Deutch's explanations of the origins of number systems and computational universality and finally through to Ethereum - attempting to explain the concepts of "reach", "universal" and "Turing Complete" and how these are connected in various domains and why any of it is important. How is Bitcoin different to Ethereum? Does it matter? No, I am not selling anything and have no "financial interest" in any of these things (the first time I have needed to make such a disclaimer as my first introduction to crypto has revealed how terribly politicised this subject is, apparently.)

Reading a short chapter from "What's Eating the Universe?" by Paul Davies titled "The Big Bang" - and adding some exposition and commentary. Also: AMA as time permits.
As always I do not monetise anything (there are no ads/I get zero income from youtube) - but if you'd like to support me just go to www.bretthall.org and follow the links to donate. Also the "superchat" feature in Youtube is something that would get to me.
