The question is, what will Ethereum look like in 1-2 years, i.e. by the time EOS is really out .... given that Ethereum keeps being improved, how much of the tech issues with it will already be solved by that time? Whereas, for some reason, instead of continuing to improve say Bitshares, Dan seems to feel the need to keep creating new coins ... that for me is the big question-mark (besides EOS's already overly huge valuation) - even granting that Dan is some kind of crypto-genius, how long will he stick around on EOS before creating another new coin with even more advanced tech?
Whereas at least with Ethereum, Vitalik and others stay and keep improving it, and putting the tech advancements into Ethereum itself rather than creating another new coin.
So while Bitshares + Steem are very impressive (and for the record, I do hold them, as well as a tiny bit of EOS), it's worth noting that their market-caps are currently dwarfed by Ethereum's (and even by the totally unproven EOS's). This might further argue for the value of the creator sticking with one thing, building traction with it, and improving it, rather than always creating another new thing. So I'd be much more excited to see Dan say continuing to improve Bitshares, than always be off creating the new next-better-best-thing.
