I think he's onto something. Once you the power projection he talks about you can't unsee it. I agree with him that a fence is a projection of power, and found it frustrating you couldn't see it. I also agree with him defence and offence is a matter of perspective. I think the encryption vs proof of work muddied the conversation a bitnwhen in fact they are kind of the same thing. Only POW is brute-forcable hashing that only proves someone expended energy vs encryption which is not brute forcable and so can't be used to tell us wheter or not someone comitted energy to an act. So the two together are essential. Once you conbine proof of real worth energy expenditure with software you bring the real world into the virtual world in a really profound way, and I think we're going to see the application of that becoming more important as AI blurs the lines between human and computer generated content. At least pow will impose a real word physical cost which might well keep us all sane.
