Have you been paying attention to Bitcoin the past few years? The immutable ethos in Bitcoin has led to very slow changes at the protocol level and no hard forks. This is a good thing for p2p money, but doesn't bode well for Bitcoin as a developer platform.

My point is that the world is better for having two types of blockchains that serves different use cases -- one that's immutable and is used for p2p cash and one that makes quick decisions and forks when deemed necessary for the sake of developers. ETC, at least as I understand it, doesn't fit into either category.
