50 X speedup sound rather impressive but it's not that much.   It's
probably
made go programs about 2 or 3 stones stronger over the few years that it
took to get hardward 50X faster about what you would expect.



But it is hardly that much. Current programs are hardly 2-3 stones
stronger ythat those in erly nineties. And if you comapare back them I
used Goliath on my 286 20 MHz computer and today I use GnuGo on my
2GHz Athlon. So in bit over decade decade computers got about 100
times faster maybe 2-3 times more effetc/cycle so almost 300 times
faster. And gain in strength is about 2-3 stones.

So 50 times faster is lot faster. It will take more than few years to
come. It may not help that much. Obviously any speed gain will help MC
type program but I doubt not too much. MC probably will not dominate
computer go in next decade. I am pretty sure we need some new ideas
still to make progress. And By Go I mean a game that is played on
19x19 board. I find playing on 9x9 boring and not really a same game.
