Yeah, it may be right to dismiss the environmental criticism as the weakest one, but I don't think the article sufficiently makes the case for that dismissal.

Yeah, it may be right to dismiss the environmental criticism as the weakest one, but I don't think the article sufficiently makes the case for that dismissal. In a system centred around the premise that money is the only thing that motivates, for thing A to beat thing B, there has to be more money to be made from doing thing A. I don't think the case has been made here (though perhaps it has elsewhere) that PoS can beat PoW on these grounds -- are there sufficient incentives to make that shift?
