Not in our lifetimes, I guess. People would still willingly embrace the fact that they are being fucked by the banks and they would do nothing about it, well that's the case for over a few hundreds of years now. Also, as long as there are governments backing up banks, they wouldn't simply disappear, not in their watch since they are also making money out of these banks and they couldn't get something out of bitcoins.
Banks are evil... Not many people agree with this idea until they're going to find out what the real reason is for them being here. They're not here to help us, they actually exist to rip the money off us.
Too many people are falling in their scam.. It sounds nice until you get into it. Nobody from there will ever give you money for without profiting off you, this is what I have learned.
They're evil but people still join them, there must be something wrong with majority of us, probably we're getting brainwashed even if people around the world have repeatedly saying that banks are evil but still use their services, or probably we're too dumb to realize that even if we say bank is evil we're still using their services.
