Almost all the traditional criteria of intelligence - reasoning, planning, decisionmaking, memory etc - are exhibited pretty trivially by standard computer programs. Nevertheless no one would think of them as "intelligent" in the sense that humans or animals are.
On the other hand, we now have LLMs, that sent the entire tech world into a multi-year frenzy, precisely because they appear to possess that human-like intelligence.
And that is even though they perform worse than classical programs in some of the "intelligence" measures: For the first time, we have to worry that a computer program is "bad at math". They cannot reflect on past decisions and are physically unable to store long-term memories. And yet, we're much more likely to believe that an LLM is "intelligent" than a classical program.
This makes me think that our formal decisions of "intelligence" (the ones that would also qualify fungal networks, swarms, cells, societies, etc) and what we intuitively look out for, are really two different things.
