I think you're both right and that there's a lot of nuance.
Central banks (who, let's be honest, are not terribly tech savvy folks nor advised by such) are still coming to the realization that a currency can be replaced with code, compute, and apps. Yikes. That sort of disruption is a kick in the teeth to folks who previously have held significant power (a currency is an expression of power). A monetary hegemony works until it doesn't. I will be the first to go on the record as a huge crypto skeptic, but I can buy crypto through my brokerage and am (unintentionally) invested in it by way of SPY->TSLA->Bitcoin, so the financial system has lent credibility to crypto (you can also trade bitcoin futures on the CME, the same exchange you can trade soybeans, oil, eurodollars, and all sorts of "legitimate" financial derivatives [1]).
Crypto is best suited for trustless systems. Can you trust central banks to not race each other to devalue their currencies? You cannot, nor is it likely their interests are aligned with yours. Their allegiance is to the system and the status quo.
I don't know what the future holds, but if technology can provide a store of value that can't be devalued on a whim, I believe there will be a demand for that service. Bitcoin and similar are the first iteration, one should expect improvements as the technology evolves. At the highest levels, this is less about a currency you can spend and about power and control, with such struggles previously confined to relations between nation states, and historically it is very rare anyone with this amount of power gives it up willingly [2].
