I know we all wanted to see the world go full Bitcoin only but it's not going to happen anytime soon, El Salvador even tried but failed. There is just not enough Bitcoiners in the world and the fiat system is just way too dominant still.

With Mastercard jumping in what’s will happen is eventually banks will just swap out the plumbing. The normies will just keep looking at the same digits in their app or bank account, but eventually, Visa and the banks will settle those transactions in Bitcoin, crypto, stablecoins behind the scenes. By the time it’s "all Bitcoin" the average person won't even realize the switch ever happened. Still far away from all Bitcoin tho.
