To their utility.
Not sure if it matters on the question "thinking?"; even if for the debaters "thinking" requires consciousness/qualia (and that varies), there's nothing more than guesses as to where that emerges from.
For my original earlier reply, the main subtext would be: "Your complaint is ridiculously biased."
For the later reply about chess, perhaps: "You're asserting that tricking, amazing, or beating a human is a reliable sign of human-like intelligence. We already know that is untrue from decades of past experience."
You're asserting that tricking, amazing, or beating a human is a reliable sign of human-like intelligence.
I don't know who's asserting that (other than Alan Turing, I guess); certainly not me. Humans are, if anything, easier to fool than our current crude AI models are. Heck, ELIZA was enough to fool non-specialist humans.
In any case, nobody was "tricked" at the IMO. What happened there required legitimate reasoning abilities. The burden of proof falls decisively on those who assert otherwise.
