So we can probably conclude that A0 is at most 100 elo stronger than SF8, which is a pretty good result for SF actually (certainly not crushing or devastating),
by which I don't want to play down the amazing achievement of A0 (even if the match ended the other way it'd still be huge)
Question remains how far could Deepmind go by training longer and using more than one 4TPU machine (assuming it would scale better than SF).
However, DeepMind certainly has much higher ambitions than claiming superiority in computer chess , I wonder why so many people are upset.
The traditional tedious way of doing computer chess still lives (at least for the top dogs) and we should be grateful to DeepMind for showing us that there's still room for improvement.
