Every one and awhile the AI will approach me with the message that roughly says "You're going to want to trade your first born son when you hear about our new discovery. Seriously, have him start packing." when I agree, it opens up the trade window. Now I can only assume this is where the AI would offer me a recent tech discovery with a perceived value for me to match, but it seems that technology trading either was never added or has been removed. Am I wrong?
