You gain the knowledge of how to create any transhuman technology in Eclipse Phase, from cortical stacks, to Cornucopia machines, to picomachines.
You don't initially understand technology demonstrated by TITANs unless you are one yourself, and ETI technology is right out, but you do understand "equivalent" extraterrestrial technology (like that of the Factors) and can research TITAN technology if you put time and effort into it.
