LOL! "Ethereum is like kids playing in the playground, pushing shit to the limits to see how it goes" yeah that's classic, but accurate. Since Ethereum has some developmental challenges, I would have to agree with you. And as far as Bitcoin goes, it's got its groundwork laid out and it's way ahead. It's so ready or further adoption.
Like you said, Steem is also complete/ready and even though a lot more can be done, that'll just add onto the value of the currency.
