I consider Napster is a good partial comparison.
It's a disruptive technology, there's been a lot of them. How many thousands of years did man use horses/carts/whatever to move stuff? Cars and trains changed all of that, presumably for the better.
The internet? I've been online since 1981, but only since the turn of the millennium or so has it done these things (America-centric view):
Nearly killed the postal service via email. There's been a postal service in USA longer than there's been a USA.
Newspapers and magazines? Adapt or die.
Greedy record companies? Ten years ago they were screaming that 'digital downloads' will kill the record industry. Now Walmart and Amazon have 99 cent music downloads.
Greedy movie companies? They wailed about piracy, but years later Netflix and Hulu are doing very well.
Bitcoin may not make Money 1.0 obsolete, but could very well change many parts of it forever.
