NOT suggestin they will look axactly like us but some common traits would seem to make sense.
Octopuses are the most 'alien' intelligences on earth, and yet people have formed close bonds with them.
People often describe octopuses as aliens and point out that there are strange convergences. Conventional wisdom holds that to be intelligent, natural selection favours species that are K-strategists, as opposed to r-strategists. Ks typically live long, have complex social structures, produce few offspring which mature slowly but have high survival rates due to high parental investment in their care. Generally they are highly intelligent and have 'culture.' Humans, other primates, and cetaceans are exemplars of this type. Rs are the opposite - they are asocial, and they produce many offspring for which there is no parental care and which have low survival rates. K-strategists are more adaptable due to the time spent learning while r-strategists recover quickly from catastrophes.

Octopuses and cuttlefish however break this rule (we don't know enough about squids). They're very smart despite being asocial, short-lived (which is really tragic), and having no care of juveniles (parents die before their eggs even hatch).
Despite all of that, there are plenty of reports by people who have interacted with octopuses.

( I really feel sorry for octopuses and wish some mad scientist would endow them with long lifespans.)
(There are parrots and crows to consider but they are also R-strategists and I bring up octopuses because they diverged from our lineage so long ago, long before backbones evolved.)
So then, the point is that apparently some intersections are possible, despite what I have written above. However, we should be careful of anthropomorphisation. Maybe we can find some commonality with weird intelligences, but just how much? Flannery O'Connor, paraphrasing Teilhard de Chardin, wrote that 'everything that rises must converge':

Does higher intelligence, despite its different origins, converge on some common form? Is that wishful thinking? Even if that is so, it looks like being something that's beyond our current intellectual horizon.
