[Immutability vs. adaptability] is now at the center of the Bitcoin vs. Ethereum competition for the hearts and minds of developers. I believe the Bitcoin core developers have more or less landed on immutability, and Ethereum core developers are very much into adaptability. It may be that it is useful to have two significant, liquid, and highly capitalized public blockchains: one that is immutable (think of gold) and one that is adaptable (think of the dollar).
There was a time when I was a Bitcoin absolutist. That changed a while ago, and I now believe that we are going to have multiple blockchains, multiple currencies, and a ton of app tokens, some with their own blockchains, some built on top of Bitcoin or Ethereum.
