The future prospect of the Vitalik Buterin's ether Fang is still bright, although it is now facing the challenges of later show EOS, AE and so on. 1$did not get on the car, this year 500$, regret, life is so melancholy, though I still wish the ETH to go all the way.
And definitely not EOS (first joke in the video above

). Even forgetting that they have no valuable product yet, remember that EOS is an ERC20 token powered by Ethereum blockchain.
It seems you didn't understand the meaning of this phrase in future EOS will become big challenge for ETH ecosystem although both are ERC20 tokens at the moment but they are working hard to build a parallel system.
