This is not a meta-question.

The definition of "thinking" in any of the parent comments or TFA is actually not defined. Like literally no statements are made about what is being tested.

So, if we had that we could actually discuss it. Otherwise it's just opinions about what a person believes thinking is, combined with what LLMs are doing + what the person believes they themselves do + what they believe others do. It's entirely subjective with very low SNR b/c of those confounding factors.
