Let's make some assumptions. Assume that today we have a go program that can get
a branching factor of 9, and the program can get 10Mnps. That means it could
complete a 14 ply search in about a month. With the kind of speed up you talk
about, it could complete that same search in 0.02 pico seconds! This also means
we could do a 30 ply search in about 40-50 days. But I have to wonder, what is
30 plies in go? Games last several hundred moves regularly. We still have to
find some method to evaluate positions with some degree of accuracy. 30 plies
sounds like a lot for a human to cope with in any game, but if no method of
accurately evaluating positions is discovered, it doesn't really matter how deep
we can search (unless we can search to the end of the game). It should be
interesting.
