What issues do you think Ethereum ae going to have in the future? Ether is remarkably resilient - it even survived the hard fork into ETH and ETC , partly because of powerful backing in the mainstream press.
Dan is a great engineer, but he lacks marketing ability (remember the stick he used to get when he was on Steemit?), and that might inhibit the progress of EOS. Just my two cents.
I see issues when Ethereum switches from Proof of Work to Proof of Stake.
