I'd be more worried about AI creating psychotic experiences in him: murder, rape, torture, self-mutilation. What's to stop some nut from doing that on his own personal private immersion system? Surely indulging psychosis would desensitize and make his acts in reality even more horrible? Or would it take away that person's urge to express his sadism in reality? I believe it could do both, depending on the person, as humans are an unpredictable breed. In another case these kinds of normally traumatic experiences could be created and used to prepare soldiers and or emergency responders and route out those whom do not have the stomach for it. Imagine virtual surgery that cannot be replicated otherwise. Pilot training. Nothing can prepare one like the actual thing, we learn best from first hand experience. On another topic altogether we could design our educators and make education work optimally for us. We could even learn or master years worth of skill and scientific literacy in minutes using super-sensual experiences to flood out the limitless depths of the inner human psyche, squeezing an Einstein out of an 85 IQ.
