The squid can see if not comprehend the fact that water continues or if it gets high enough that there is a boundary between water and air. If indeed it isn't able to see that there is more it would not merely be because of lack of specific knowledge but because of a lack of even basic analytical tools to reason abstractly, communicate between individuals, and pass down analysis between generations over time.

I think there is a reason to believe that this represents a unique threshold rather than one of many and that even highly advanced beings would be fundamentally comprehensible and describable even if their technology is not in a way that probably isn't true of the squid because our abstract reasoning can represent the basic facts needed to describe what they are doing even if it misses the why or how.

Even a biomechanical hive would have greater longevity and resources by expanding even if we don't much recognize what they are doing with said resources.
