I would love to see EOS, and other new application centered coins succeed, as I believe both EOS and Cardano are huge players, but, I don't think EOS will make a huge impact anytime soon.
We see that in the crypto-space, name power means a ton, if it didn't Bitcoin would be nearly evaporated at this point. But, because Ethereum is already very established, and known as the "revolutionary" coin (which it is) it will remain the head of the application based coins. I simply don't think EOS will be bringing down the Ethereum behemoth anytime soon.
