First you said "...but independent Blockchains will die..." (maybe true and makes sense), than you said: "... ask yourself why someone would transact with NEM over Bitcoin, ETH, Nxt, etc...." (means eth, nxt, ETC !? is better than NEM? That´s nonsense, because i ask myself why eth, nxt and etc are better than nem? Especially in this stage of development). Or do I understand something wrong?
yes. he tries to tell us that we need to attach blockchain nem to blockchain btc. but we have much more the best blockchain than at btc therefore i wouldn't begin to attach on a place of devs blockchain nem to blockchain btc even if it is possible. i think that it's possible, but we it don't need to pull on ourselves a network which in future will die and us for itself will pull in a grave.
