The Evolutionary dominance of the "hive" mind.

It is a common theme in scifi of individualistic humans meeting a species with a collective conciousness.  The model is social insects like ants, bees, and termites, where the individual organisms are merely constituents of the hive.

The usual result is that the humans recoil in horror, particularly if the hive species attempts to incorporate humans into such a collective.   E.g. The Borg in Star Trek.

When brain-computer interfaces become practical, that technology combined with wireless networking will lead to a human version of a "hive" like collective conciousness.  What is more the collective will be competitively dominant over non-networked individuals.  This is the case since those who are not networked will not have access to information relevant to survival, while those who are networked will.
