I base my arguments on three important points that really can not be refuted: (1) deep thought (deep blue's direct predecessor) was the first (and only) program to produce a 2650+ performance result, playing games only against GM players, at 40 moves in 2 hours only for the time control. It did this over 25 consecutive games (intervening games could not be ignored if the result was bad). No other program has yet accomplished this. (2) deep thought won every computer chess event it participated in, running at about 2M nodes per second, from 1987 to 1994, losing just one event (hong kong) due to a communication failure that resulting in it moving too quickly after the re-start and losing to fritz. (3) deep blue was 100x faster than deep thought 2, with more chess knowledge than deep thought 2, and this is the box that beat Kasparov in a 6 game match. It is certainly possible that todays fastest computers, running today's best commercial programs, are playing at an equal level when compared to deep blue, although the Kramnik/etc matches were played at faster time controls generally, than 40 moves in 2 hours. But at best the best micros of today are maybe as strong as the 1997 deep blue system. Far from being far superior to it. Based solely on the observations given above. Each of which can easily be verified multiple ways...
