I guess I'm not sure what your point is. If you understand "thinking" to be a highly advanced capability that millions or billions of people can't do, sure, perhaps it's true that GPT-4 is not "thinking" in that sense. Most people understand the term to be more broad than that. If a four year old tries really hard to compute 4 + 16, I'd definitely say they're "thinking" about it, even if they don't get the right answer or make some silly mistake I can easily point out.

Literally millions or billions of people are better than me at a significant number of intellectual tasks
