Cage had started the Share project years before when he was still working at the lab full time. He had been thinking about the way social reinforcement seemed to energize recreational drug use. Most users preferred to get twisted with other users, at drug clubs and private parties or before making love or eating a fine meal or free-fall dancing in space. If socialization enhanced pleasure, why not try to find a way for users to share an identical experience? Not just by creating identical surrounds but by synchronizing the effect on a synaptic level. Direct stimulation of the sensory cortex. A kind of artificial telepathy.
