at any given moment there will always be a nonzero fraction of the BTC community who understand a facet of a problem extremely well and have a good idea to solve it. it is never guaranteed they will convince the majority. when they don't get their way they leave. constant brain drain. paul is gathering most people who understand what sidechains really do and he is evacuating them and BTC will lose these people. I will sound like a broken record but again, this sort of thing has already happened multiple times.
