Even if Einstein's General Theory of Relativity got a lot of traction as well as application starting in 1960's (let's assume you are correct), he didn't live up to that anyway. In this manner, if Bitcoin succeeds big time in, say, 22nd century, we are unlikely to witness its triumph, so it is definitely not something we should be looking and still less waiting for. Thus, if Bitcoin is to make a second coming which would be better than the first, it should hurry up
It should, and it will. Things are happening increasingly faster these days. What took 50 years back then can take 15 years now. And considering that 10 years have already passed, it seems fair to say that we are close
But people are tremendously impatient these days
So if Bitcoin doesn't deliver any time soon, they will definitely start complaining. Wtf, Bitcoin's price had been stuck in a tight range between 3.5k and 4k for nearly two months (maybe even for a little longer than that), and folks already started wining that the market was boring. But that's not my point. If Bitcoin is going to rise and shine again, what should that be if not hype (the odds of which are small anyway)?
Among other things, blockchain technology, and Bitcoin in particular, can be used effectively for fighting corruption in the government sector. But those who are in power are either too lazy or too stupid to grasp the idea, and there are also others who simply want to continue plundering their countries
The powers that be will never agree
