I keep seeing people credit Yarvin with the rise of the alt-right or MAGA but I don't see any elements of NRx in MAGA other than the edgy attitude. None of his ideas have been implemented or if they have it's by accident. Of course his writing is so obfuscated I guess he could use hindsight to twist his own words into something like a correct prediction.
That said, he does raise some interesting points--in extremely roundabout ways--and it's incredibly telling how different people react to him. The amazing amount of butthurt und sturm und drang that comes up whenever urbit is mentioned, for example, is almost always due to political/tribal stuff and not due to technical deficiencies or the deliberate obfuscation of whatever ideas actually might be there.
I think he's basically riding coats of the populist MAGA movement at this point in an almost ESR "I helped make this" sort of way, and while an interesting footnote in the evolution of NRx he's basically just an edgelord with some extra money.
