I mean, of course they have some level of intelligence to be able to do
all they do, such as build huge colonies, fight wars, raise crops, etc.,
but are they by any definition of the word truly intelligent?

Perhaps this is why really advanced ETI do not bother with us: We
also have a society with similar features, but they don't contact us any
more than we try to talk with ants because we aren't considered smart
enough to communicate and understand them at their levels.

And just hope they don't treat us like construction workers would treat
an ant colony at a building site. They don't intentionally want to harm
the insects, but they don't care if they are in the way of their project,
either.
