12. Yes,

The Prime Directive is not just a cool, sci-fi show idea, it is an intelligent choice based on real world history.

You can see the impact that an "advanced" culture has when it impinges on others, especially haphazardly. Consider what has happened to the indigenous American Indian tribes in the wake of the Western invasion as only one example.

The tendency is for even basic exposure to have a tremendous impact that can rapidly change or even decimate aboriginal culture, religion, etc., and not for the better either.

In that case, the Prime Directive is a reasonable speculation as to a more advanced, alien species keeping a distance and observing us or waiting until we reach a critical threshold that they deem acceptable for contact. It also could indicate some sort of concern, empathy or compassion for developing species in the Universe.

One wonders that, other than in our fiction, if we would be doing something similar at this point in our evolution.
