Author's claim is pretty strong: that human intelligence and what is called GenAI have no common ground at all. This is untrue at least intuitively for the entire field of ML. "Intuitively" because it cannot be proven or disproven until you know exactly what is human intelligence, or whatever the author means by thinking or reasoning.
>Arguably AI researchers ought to have a fairly well defined stance of what "intelligence" means and can't use a trick like "nobody knows what intelligence is" to escape criticism.
If you don't formalize your definition, the discussion can be easily escaped by either side by simply moving along the abstraction tree. The tiresome stochastic parrot/token predictor argument is about trees while the human intelligence is discussed in terms of a forest. And if you do formalize it, it's possible to discover that human intelligence is not what it seems either. I'm not even starting on the difference between individual intelligence, collective intelligence, and biological evolution, it's not easy to define where one ends and another begins.
AI researchers mainly focus on usefulness (see the definition above). The proof is in the pudding. Philosophical discussions are fine to have, but pretty meaningless at best and designed to support a narrative at worst.
