Once Bitshares, Maidsafe, Ethereum and Supernet are up and running 'established' there will be no looking back. Can't wait to see what this year has in store, but...
While I agree that different Bitcoin 2.0 project should compete on a feature level, I think that competing about resources slows evolution down. If every project requires its own resource supported blockchain then each individual blockchain becomes weaker against attacks, like it happened a few times in the past.
There needs to be a common blockchain, built by aggregating all the resources, that serves as a platform on which to build new innovative projects. Otherwise requiring every project to come up with the necessary resources to launch is a major roadblock and is wasteful with respect to resources.
There is certainly an advantage to having a shared ledger with common network effect.
The question is when to standardize? Innovation is very rapid right now. Standardization tends to inhibit innovation.
What if the design of all life forms had been standardized on the architecture of the trilobite?
So we are in a Darwinian period where eventually a standard will emerge because most people find it most cost effective.
I would not expect any existing life form to become the ultimate Homo Cryptosapian solution.
In the meantime - grab popcorn, sit back and watch a modern repeat of the Cambrian Explosion.
