In humanity's current ignorance, all sorts of supposed advanced examples abound - Jesus, Angels, Demons,
And various aliens.
It would be nice if we had a reasonably documented account of an alien culture that we might learn from. This way, we could judge stuff like NSA spying, Socialist economics and much more. We could learn what's possible in an advanced ET culture - as well as what We May Have To Put Up With.
I guess only the Tall Whites might qualify. I understand that they have clearly defined roles (and rank), strong family attachments, side arms (and itchy trigger fingers), a strong sense of fulfilling agreements and maybe gadgets that keep them linked. Doesn't sound too awful (as long as they don't shoot you)
