It isn't quite an opinion.  DT definitely proved itself superior to micros.
Over a 10 year period.  DB played several games vs Deep Thought as Hsu and
Campbell were testing it.  It was far superior.  In this case, since DT >
micros, and DB > DT, I think the transitivity holds across all three, because
DB wasn't DT minus something.  It was DT plus a lot.

Here is another angle to consider:

Deep Thought's processor was a 1987 piece of hardware.  By 1995 it had proven
itself to perform at a GM level, with three numbers you can choose from.  An
official USCF rating of 2551 over almost 50 games.  A TPR over its best 25
consecutive games of 2650.  And finally if you only count deep thought games
without the first few which had horrible hardware problems, it had a TPR of
2590.

All are impressive.  _all_ are 1986 hardware (the single processor version,
called "chiptest" first played in the 1986 ACM tournament.)

So 1986 hardware produced a true GM-level machine, based on enough games that it
can't be considered a fluke or accident.

Today, Rebel is trying to produce the same result, on hardware that is 14 years
newer.  It is _very_ close to 2500. It isn't as close to 2650 (by taking the
best 25 games vs humans).  But it might make 2500 by the Summer with a little
luck.

With the above data, how far _ahead_ of Rebel (in terms of time) would you say
DB-2 is?  Rebel has yet to do what 1986 hardware has done.  No other program
has yet produced a GM-class rating over 25 games.  My guess is, as it always has
been, at _least_ 10 years behind.

We can discuss any of the above that you like, of course...

We have DT's results documented quite well.  We have (thanks to Enrique)
Rebel's results so far.  A few more months will push this to 25 solid
games...  1986 vs 1999 hardware.  fairly close comparison in performance.

Of course, we have the problem of the 1997 version of the Hardware to deal
with. :)
