End of paper money? that's bit over the top. You can't just abolish something that took years to build, BTC is still very new.
I don't think that it is, like, at all. I personally admire his capacity to build and if i can emulate even a bit of the great treats he has i could build cool things too since i have a lot of ideas.
Paper money will become(if it's not already) a burden for some governments and it will certainly be eliminated in the future. It's not really needed as long as a pretty good payment method is around that allow us to pay absolutely everything with virtual currency.
For example, in Venezuela you can only get like less than $1 everyday out from the bank. Yes you can't do practically anything with that. Imagine if instead of printing more and raising the inflation, everybody accepted virtual currency?. There wouldn't be a problem at all.
