Ethereum is a developer platform that needs to move quickly, and that ethos doesn't work for that type of platform
I don't see any relationship between the speed of development and blockchain having an ethos of immutability, irreversibility and opennness. ETC is in a perfect position not to lag behind ETH as far as developement is concerned.
And blockchain without any ethos is pointless IMO. If you scrap the ethos part, there are more efficient ways to achieve the same results.
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.
How so? Are you saying that ETH will develop quicker because each time they screw up they will just hard-fork? That's nonsense.
You seem to be confusing the immutability issue with the governance issue. What stalls Bitcoin's development is the unresolved governance issue, and sticking to the immutability principle affects BTC price but has nothing to do with the speed of developement.
