They don't have to prepare the world for it because they are the ones who are making these systems. And in fact, it will continue to be used because that's how the government has set each country that they govern. As for the stable coins, they might push it or not. We heard of the CBDCs but what's with them right now? And so, if they'll have people to get into either of these with that kind of yield, then there will be the banks that will be assigned to it or exchanges will have to work on with them or has to work like them.
Well, the CBDC thing isn't happening "right now", but they are all looking into it, and the governments of the world do not do things very quickly, as we all know; it takes time. ETF, for example, took nearly 5 years from being an idea to being a reality, and this was pushed by BlackRock like a nation sized company, so if there is no BlackRock behind CBDC to push now, imagine how many more years it will be. But that doesn't mean it won't happen; it's a digital way of printing money and taking real money away from people.
Governments will always want something like that; they will even desire it. It's not safe right now; they are worried about the potential hacking, because if they ever do it, we are going to see THE WHOLE WORLD going to attack it, and they can't take that risk. Is there a way to do it without any risk? There is none, so it will be postponed more and more. Hell, even the FBI got hacked, and all the info was leaked, so of course anything could happen, and that is why they are postponing until they are certain.
It does need solid backing by first, the government and with the likes of BlackRock or whichever big company is there to finance and implement it. I thought that there's a big development with it but they seem to have been delayed. Because when I've first seen the news, it became a trend that almost every country have been interested into it. Those with understanding of how it actually works. Now, it probably might have been delayed or totally abandoned when they don't have to complicate it by themselves and by just doing a stable coin for themselves or by adopting one that's already been established. Otherwise, just as you said, it will be postponed just how the Libra project did and other likes.
