He doesn't say 'replaced',

"I think we evolve to Bitcoin 2.0 or 3.0, using the same blockchain technology, but with a way to make the

and "But will it be Bitcoin? My best guess is that it will not be Bitcoin as currently constructed but rather an evolved version."


Isn't that the idea - as with most software - to evolve?
