I think both sides of the argument have truth in them. Of course the good 2013 players would beat the good 2008 players because the game has progressed since then. This is the case for alot of things, like if i went back to the 80's i would be a pro skater along with all of my friends because it has progressed so much. I also agree with spencer 555 when he says the skill in tao is capped at a certain point and if two good players are playing their best, it will come down to luck. (If sets are neutral)
