He was right, though.  The fact that BCH has fast difficulty adjustment and bitcoin doesn't while the Chinese control most of the hash power is gonna be mega-problems for BTC.  I imagine all BCH has to do is NOT DIE and it will cause Luke Jr to be forced to fork BTC to change difficulty adjustment.  Since BTC is now forced to fork, people will probably want a bunch of other changes like PoW algo change as well.  It's a real can of worms here.

Having said that, I vew any chain with a fixed blocksize and low scalability being nothing more than an extortion, rent seeking usury system.  If you're promoting the whole planet pile into a 1 MB blocksize coin, all you're doing is promoting usury.  The only way to fix that paradigm is use a scaling blocksize like Monero.
