I like how Max Tegmark frames it by considering Birds and Flight and how we built Planes that can also fly. It turns out Flight, as an action on its own, is not so difficult if you throw enough energy behind a particularly shaped collection of parts. Intelligence, as a behavior observable in the world, appears to be similar in that it emerges in stages at scales as we are discussing. And just like inventing airplanes caused us to say 'all things that fly are not birds', now we may start saying 'all things that display intelligence are not us' (where intelligence is => human level intelligence and "us" could be swapped out with alive/sentient/conscious/etc at least for now and perhaps in all cases)
