It's far from what Ethereum is, and there's still so much work that needs to be done. The only way I see EOS surpassing Ether is if the Ethereum core devs mess up and delay Casper for too long, then EOS has a chance of catching up and overtaking. Since EOS has no legacy, they can move much faster than Ethereum, and that's the only thing I see of value right now.
Yes. It is briliant idea, but probably it is too late. The main question is - Will Ethereum overtake all dapps market before EOS relise or not. Hopefully not and there still be enough space for dapps.
EOS promise millions transaction per second and free dapps build. It is BIG.
I think it could take a place between ETC and ETH. It should surpass ETC but will not surpass ETH.
