The current fiat incentivizes debt and investment. Bitcoin incentives saving.
We are at near 0% interest rates and need a way to transition out of this debt/investment euphoria. Governments want to do this without crashing markets (or if it crashes at least have a soft landing). Somehow I think bitcoin can provide this soft landing and enable governments to slowly raise rates without shit hitting the ceiling.
By debt/ investment euphoria, I guess you mean the availability of cheap credit due to actions like Quantitative Easing. Why do you think that the governments want to change this? All I've noticed is major economies printing more and more. Maybe i misunderstand. An explanation would be great.
Maybe eventually bitcoin gets mass adoption and becomes the global reserve currency. And another 50 years later, the world ends up having another problem - too much saving and not enough businesses taking risks and innovating. Then another global reset and somehow we are back to the fiat world. If we look at what's happened in history, we started with sea shells (soft money) then gold (hard money), then fiat (soft money) then bitcoin (hard money) and maybe eventually we'll be back to fiat (soft money).
Bitcoin becoming the global reserve currency in purely official terms is something that organizations like IMF will fight tooth and nail. The best bet is with private corporations deciding that enough is enough and they need an alternate to the fiat. During his interaction with Cathie Wood and Jack Dorsey on "The B Word", Musk said that its ridiculous that the cash reserves of Tesla pay out interest (due to negative interest rates). He also endorsed some pretty far-reaching ideas about how government is just a corporation with a monopoly on violence. If you extrapolate those ideas and enough corporations reach the conclusion that they need to do something about it, coupled with the realization by masses that they need bitcoin, bitcoin will become the de-facto alternate to fiat. A global reserve currency for citizens/ netizens.
