Like all prior paradigms, bitcoin is forever, just as gold, fiat, debt, and expansion will remain. It will be up to each person to choose which modalities they subscribe to (and have the cognitive capacity to grok). I don't think the age of bitcoin has even really started yet--we are still very early. With the parabolic stacking of new technologies, we will see multiple standards start to be simultaneously used. In my case, I'm using bitcoin as a store of value, and credit/fiat as a form of spend. I don't see these going away, but as CBDCs are introduced, it will be a challenge to avoid control.
