I think one of the most interesting trans humanism feature would be to enable transhumans to do telepathy with their eyes with everybody around them, to enter in the mind of someone else when they want, to transmit images also with eyes and to give emotions too, this would enable society to fight criminality and find criminals. Also another feature would be to have lights emanating from our eyes able to send more information and see in the black environment. No secret world, a new way to communicate.
