Do you know how Deep Blue searched? How will we reach those fantastic speeds? Faster hardware does not inflate ratings. It raises it by a logarithmic amount for each increase. It is estimated about 50 ELO. So, suppose we have a program with 2500 ELO and we want to get to 2800. 2500 + 50ELO/doubling * 6 doublings = 2800. Sounds pretty simple, right? But if it takes 500 Mhz to get 2500 ELO, then it will take: 500 * 2 * 2 * 2 * 2 * 2 * 2 = 32 GHz to achieve it (roughly speaking). IOW, more horsepower is a tough way to make chess programs play better. There is also evidence (according to some) that the increase in speed has *diminishing* returns. Hence, it may take a terahertz to get there. Don't know of any material that could do that, not even a Josephson Junction.
