Best POS argument ever. Sorry, not to pick on this one. All of the arguments in this thread were similarly “incisive”, except for @artkor’s. (His argument was not logically connected to either POW or POS; but at least, he said something substantive instead of merely jeering at Dorsey or cheerleading for POS.)

**POS has nothing for it but groupthink based on trend-following, fads, and economic mirages.**
