I don't agree with such an unforgiving attitude at all. It works for tournaments but not for demonstration games. You don't want to give fuel to those who argue "yeah, but the computer can respond in a millisecond where the human has a physical response time of at least half a second."

In demonstration games what is important is the spirit. And it doesn't do the computer-Go community any good for a program to persist in an absolutely lost position, play one for a hundred more moves that the human is physically unable to play in time.

It will have to give one way or another. I also don't like the fixed time-limit very much because Go has such an unpredictable game- length. So Fisher time could be a solution. On the other hand, once the level of the programs becomes well established, programmers could also make it resign a lot sooner. In a 1,000 ELO game a 99% win-rate might occasionally still turn around. But they'll probably find out that as the level gets higher, say 3,000 ELO, you end up never turning around a 90% win-rate. Or maybe even 80%. If programmers want humans to play their software then they have to be also a little accomodating in that respect, even if that means giving up a game where you might still win once in a thousand times.
