I am not going to argue about deep blue here but I think that it is wrong to assume that no programming tricks are going to offset speed difference of being 100 times faster. I believe that the only reason that programs failed to do it is that people failed to write the right program. I think that the task of offsetting speed difference is relatively easier when the hardware get faster because better search algorithms can increase the difference between programs at longer time control.
