I'm inclined to blame the author's negativity on his obvious conflict of interest. At least, my understanding is that he recently began working for a group that competes with Bitcoin in trying to connect traditional banks and (non-Bitcoin) blockchain technology. He has an incentive to scare people away from Bitcoin. Not saying there are no scaling/social/whatever issues in Bitcoin. But the author seems to be conflicted. Disclaimer: I own a few Bitcoins, and thus hold the opposite conflict of interest.
