Frankly, I am baffled by his and Fitz's design.
When they started explaining the LMD project, I thought it was going to be a series of remote-controlled avatars. Put your VR headset on, with a neural interface and everything, and get a live feed of a body just like yours. Do everything you could normally do but without actually being on the field. In that context, "Aida" would be a program meant to test the body's reflexes, default posture and other dynamic aspects of the deception.
Instead, we are going replicants. Autonomous duplicates of agents. Something that would require a full-blown AI.
