That's how I see it as well, it's not going to happen in the short term and I've come to terms with the fact that it might never happen. I think huge established payment networks like Visa and Mastercard won't be replaced and will likely ride the stablecoin/cbdc wave due to their huge network effects, I don't see them going away anytime soon.
I'll for sure keep saving in Bitcoin for the reason you outline but we gotta be real, the original goal and ethos of Bitcoin hasn't materialized. I even think that spending Bitcoin is irrational if you have acces to fiat or stablecoins.
Really enjoy your levelheaded, rational and nuanced takes!
