Yes, but if you read the article again carefully, you will see that they are not
claiming an immediate speedup of 10000. Maybe a speedup of 3 in several years,
which just continues Moore's law.

That _might_ be reasonable if endgame databases are only probed at the root of
the tree. But most programs probe them during the search, so they should
definitely not be taken out simply because computers are getting faster. If
anything, they become more useful as computers get faster.

I disagree. You have to remember that processors today are thousands of times
faster than processors 20 years ago, but that doesn't trivialize the importance
of a good algorithm. TSCP is pretty bug-free, but that doesn't mean it can
compete with, say, Junior.
