I think the argument rather is that there is not such thing as AI that is not human-alike. The traits that AI exposes, if I get the point made here correctly, are traits that existed in the training material, even though not evident for the human eye. It is a mirror-like reflection of humanity's traits found in the source material, an Egregore* of a sort.

The intelligence emerging, or whatever is emerging, more or less follows human traits, the CoT exposed is very human-like etc. Even though we should not anthropomorphize AI as being sentient or conscious or having a soul, etc., we have to remember that the source material is still not alien writing, or concepts that came from Sirius or emerged from a wormhole.

The concern is really nobody reads (or have ever read) 77 TBs of information in order to summarize the most evident traits in it, and there is a fair chance, that where humanity stands today, there are so many bad/damaging traits recorded in this corpus. Then there is a chance the most important features are on a level (or have dimensionality) that is incomprehensible, that humans are unable to reason about (or only few can), because such amount of information is very hard to reason about, or because we don't usually facilitate fractal dimensions when we reason about text and everyday concepts,... or something even more bizarre.
