I've always wondered about the whole 'logistics' of steem/blockchains; of course modern computer processing speeds are hard to even wrap your head around, I can't help but sometimes wonder how 'long term' feasible block chain technology is... I mean every three seconds there's more data to be processed. Admittedly I'm not a computer scientist and I'll leave this speculation up to people that are more informed on the subject. But I like what you're saying!
