In the context of "AI", the use of the word "intelligence" has referred to human-comparable intelligence for at least the last 75 years, when Alan Turing described the Turing Test. That test was explicitly intended to test for a particular kind of human equivalent intelligence. No other animal has come close to passing the Turing Test. As such, the distinction you're referring to isn't relevant to this discussion.

> Personally, my take on this is that intelligence is not a useful term in philosophy nor science.

Hot take.

The Turing test was debunked by John Searle in 1980 with the Chinese room thought experiment. And even looking past that, the existence, and the pervasiveness, of the Turing test proves my point that this term is and always has been extremely anthropocentric.

In statistics there has been a prevailing consensus for a really long time that artificial intelligence is not only a misnomer, but also rather problematic, and maybe even confusing. There has been a concerted effort the past 15 years to move away from this term onto something like machine learning (machine learning is not without its own set of downsides, but is still miles better then AI). So honestly my take is not that hot (at least not in statistics; maybe in psychology and philosophy).

But I want to justify my take in psychology. Psychometricians have been doing intelligence testing for well over a century now, and the science is not much further along then it was a century ago. No new prediction, no new subfields, etc. This is a hallmark of a scientific dead end. And on the flip side, psychological theories that don‘t use intelligence at all are doing just fine.
