Pointing fingers at another visionary that may or may not be bitter for a hack is kind of preposterous. That being said, the guy stated his opinion based on what he thinks is possible. If @ned, @dan and the rest think otherwise and so far try to prove it, more power to them. I, for one, believe in Steemit but I realize I am not well versed in crypto to imagine the burden to take this project to a huge scale.
Good luck to us.
Good luck to them.
