Ingenious piece of work
Synergy points at Human Melt With Machine to man-machine. But I sense a synergy of soul in the human condition of two poles:
Synergy of Soul:
Soul is an energy with two foci with a weak epicentre in the middle of Reason. The I is a cart-driver of two horses tearing off and away into two directions. Bipolary forces of an "I" are in chance of making comprimises with them throughout the "I": Eros & Thymos. Thymos contain reason-orientated forces like pride, generousity ... - while Eros contain desire-orientated forces like longing, obsession, desire of materialistic possession.
As to be seen, you inserted + and - in context with 1 and 0 as a floor, which resemble binary hardware informatics. We see pipes connecting with heads of humans, in poses, giving an impression of being distorted, or at least disturbed. They are connected, but not clarifying by their telepathical exchange, instead they are confusing eachother. They do not gain enlightenment, but confusion. So that borders and distance of each "I" from each "You" is important to keep your soul clear, otherwise Identity will whirls down the plug hole and a Borg collective will emerge. Then we can talk of synergy of thoughts in a collective mind, collective ghost, but no soul, anymore
