Ok, this may be a question for Brad, but maybe someone else knows. How much do the AI's design their own ships and how much do they just copy from the player?

I ask because the other night I was in a pinch militarily and started using cargo hulls loaded with a ton of guns. They were used as disposable ships and relied on superior numbers. Additionally, they were fast a cheap to build! Anyways, a while later I find the Terrans have done the same thing, using cargo hulls and loading them up... Only this time, they put weapons and defenses on it (something which totally defeated their purpose)

So is this just a case of an AI seeing my design and figuring there must be some merit to it and copying? Or was it a cosmic coincidence because I have never seen an AI do that on its own,
