the dan olson video is mega spot on in one particular way. these zero-trust distributed networks approach validation in the most brute force way possible and it makes blockchain completely unscalable. there's simply no way that crypto becomes an acceptable currency because the ledger will start to shit itself before it ever meets demand. the coins that don't fucking get stuck for hours processing transactions or require hefty additional fees to move coins around are only fast because they're niche and underused. there's simply no use case where blockchains are preferable to traditional payment operators and it's doomed to remain as a hobby horse for the most detestable people online.
