The article you linked discussed reasoning. That's really cool. But, consider that we can say that a chess game computer opponent is reasoning. It's using a preprogrammed set of instructions to predict out to some number of possible moves ahead, and choosing the most reasonable. A calculator, essentially, it is in fact reasoning. But that doesn't have much to do with intelligence. As we read in the dictionary, intelligence implies understanding, and we certainly can't say that the Chess Masters opponent from the Super Nintendo literally understands me, right?
More to the point, I don't see that any LLM has thus far exhibited remotely any inkling of understanding, nor can it. It's a linear regression calculator. Much like a lot of TI84 graphing calculators running linear algebraic functions on a grand scale. It's impressive that basic math can achieve results across word archives that sound like a person, but it's still not understanding what it outputs, and really, not what it inputs beyond graphing it algebraically either.
It doesn't literally understand. So, it is not literally intelligent, and it will require some huge breakthroughs to change that. I very much doubt that such a discovery will happen in our lifetime.
It might be more likely that the marketers will succeed in revising the dictionary. We've seen often times that if you use words wrong enough, it becomes right. But so far at least, that hasn't happened with this word.
