There aren't enough games played between these programs and humans under
tournament conditions to generate a successful conversion.  There is enough
trouble trying to convert ratings between the human scales.  None of the top
SSDF programs have real FIDE or USCF ratings.

They are very strong.  Whether they are as strong as GM's or IM's or what is
open to contention.

If they aren't as strong as typical GM's already, they are within a hardware
generation or two of being that strong.  This doesn't mean that they will be
able to understand every position as well as a GM, it simply means that they'll
score 50% in tournament play on a computer that you can lift.

In 1995 at the Hong Kong WCCC everyone was asked when they thought computers
would be as strong as the world champion.  My pick was not published in the
ICCAJ, presumably since I was a nobody.  My date was 2005, and I'm still
sticking to this four and a half years later.
