Assuming by "hard" you mean "physical" bitcoin, I have to say it is not going to happen. The world moved to digital form a while ago and (ignoring bitcoin) everything is becoming digital including money. I can't remember last time I paid with cash (ie. physical money).
This idea must be out there already, and I am probably just behind in what's going on in hard wallet technology, but it seems to me like that could be the key to cryptocurrency's being a viable alternative to centralized digital currency/social credit/tyranny.
The way cryptocurrency would become a viable alternative is when it offers something different and solves some actual problem. In case of bitcoin that is the globality of it alongside the decentralization and some other factors. If cryptocurrencies started following down the same path (physical form requires centralization) they lose their only purpose to exist.
