From our WO friends - thanks @cAPSLOCK
I knew as soon as I saw a summary of what was said I would need to watch it just to clarify whether what someone summarized was accurate or their personal interpretation. For example, cAPSLOCK mentions that Elon Musk suggested a few ideas about centralizing Bitcoin or at least got challenged by the moderator that his ideas would make it less decentralized, and
normal users shouldn't need to run nodes. I wasn't expecting that, since I would like to think that Elon Musk is smart enough to understand that much of the appeal for Bitcoin is its decentralized nature, and how the community can contribute further to its decentralized nature.
