There's a fair amount of evidence that intelligence evolves in different forms.
Kind of like the eye.
The eye has evolved several independently different times through evolutionary history on Earth and there are many types of eyes. ie: your eyes are
different from the compound eye of a fly as they are from birds, as they are from sharks and so on.
It's starting to look like intelligence could be the same. It could be evolutionary pressures lead to something like intelligence developing
eventually as a matter of time.
Within our own planet there are several types of intelligent animals with complex language, social structure, etc.
The fact that they don't wield iPhones doesn't mean that cetaceans aren't intelligent.
Then there are things like ants who seem to have distributed intelligence. While no individual ant is intelligent the colony exhibits signs of
We have to be very careful in defining intelligence. Human chauvinism often can blind us to other non-technical intelligence on our planet.
That said, the most detectable intelligences will have to use technology in some way.
However absence of finding technological intelligence does not mean we are the only intelligence in the Galaxy much less universe.
It will just mean we'll have to look a lot harder to rule it out entirely.
Perhaps the greatest argument against intelligence being the exception to the rule is the fact that we are here discussing it.
The galaxy is far older than our solar system so there's been plenty of time for other planets to cook up intelligence elsewhere.
Evolution is not something where all worlds started at the same time. We're on the young side of things when it comes to planetary systems so the fact
that it took 4.5 billion years to produce us is somewhat less relevant in the context of a Galaxy that's 12 billion years old with plenty of 6,7,8,
and 9 billion year old star systems.
Head start anyone?
As for the Fermi Paradox it falls down when you take human chauvinism out of the picture.
Why don't we see aliens all around us conquering the Galaxy? Because there are probably plenty of uninhabited worlds for each one that is inhabited.
There's no need to go stirin' up the locals when there are perhaps hundreds of other planets with no one on them within reach of such a spacefaring
Not to mention not all creatures on Earth are the expansive/social type. It could be that type of mindset is rare in the Galaxy.
