Replacing Bitcoin now would be like trying to replace gold with platinum or replace HTTP. I rather suspect that replacing Bitcoin with something new and improved might first be like replacing Lycos or Excite (used as a search engine) with AltaVista, and then later like replacing AltaVista with Google. We won't know what a currency with true critical mass looks like until we see one. I can't predict what important feature differences the next electronic currency will offer that provide more user value than Bitcoin offers, but it's quite plausible to me, given the history of technology, that Bitcoin hasn't closed the market to other entrants yet. From a nephew comment: Reddit has become integral to the culture in a way comparable to Twitter and Facebook Nope.
