Personally, I use the terminology in much the same way as Heikki. I use the word mistake to describe (for example) a move that loses a large group, but does not change the game from a win to a loss. It makes sense to me to generally apply mistake to any move that loses points relative to the

Yes, we heard that argument for years in computer chess and it never happened. Do you have some kind of basis for believe that? i wouldn't argue that future algorithms can't be time-doubled beyond the existing skill level of people, just that the current evidence is weak that we already

A lot of this interesting discussion has been about whether humans can make use of extra time. Some participants ( such as Dave Devos ) believe that, after a certain point, humans cannot improve their rank, at least not linearly with respect to time alloted. Fair enough; we humans require

If you guys are correct thinking the nature of the game is such that humans cannot improve with time, then the computers will pull ahead more and more at longer time controls. let's adjust this to avoid the strawman and say that the counter-argument is that humans cannot improve much
