Ken Thompson, with all respect forgets to mention something,
that's that there is nothing to earn with computer-go.

You get what you pay for.

Sometimes someone starts a go program first, in order to figure out the
above later. Instantly work stops then and worlds strongest go  
program no longer
gets maintained, let alone gets improved.

A few hobbyists will continue and progress very slowly as a result  
now at clusters,
using worlds most inefficient search that exists in game tree search.  
They didn't
discover even yet how to use efficiently hashtables (which reduces  
the search space

In short zero Einstein's in computer-go so far on the search front,
whereas the hardware they can get their hands on for computer-go
is big, and there is a lot possible in computer-go, forward pruning  
and selectivity
works better there than in chess (to say polite). Hopefully a Chinese  
one day for computer-go search algorithms.

They already found a lot that works for computer-chess.

For super selective search however you definitely need a few clever  

It is interesting how you try to grab attention for a game where the  
strongest current commercial
go-program sold less copies than that past 24 hours there was posts  
on this mailing list.
