Oleary is a tool, he's not a liberal tho! He'll shill whatever makes him money why he can't have a solid intelligent opinion on any innovation until he sees $$$. I bet they are getting paid to shill the green energy thing or else he would be bitching about it and want the cheaper coal powered. He used to call green energy stupid a few years ago. Everyone is allowed to change their minds sure but he only adopts the popular opinion, like just siding with the winning side all the time like a yes man, why he's rich in the first place. He'll shill actual shit if it makes him a million or 2. but I could never take advice from someone like that. As for the waste of energy argument, I'm sure the current banking system wastes much more energy than bitcoin could ever dream of.
