...this is a bit nitpicky. But the localisation for Sentient combat computers and Pre-Sentient species recently changed from Sentient to Sapient. Why? It was right the first time. Sentient means self-aware, Sapient comes from the Latin word for wise, and since we somewhat pompously decided to call our own species Homo Sapiens, Sapient now also connotes human or human-like. So now we have Sapient computers, wise and human like? Pre-human species? Doesn't make too much sense to me.
