Virtual sex with computer-simulated partner will exist

Ray Kurzweil : writer, futurist
Devices that deliver sensations to the skin surface of their users, i.e. tight body suits and gloves will also be used in virtual reality to complete the experience. "Virtual sex" in which two people will be able to have sex with each other through virtual reality, or in which a human will be able to have sex with a "simulated" partner that only exists on a computer will become a reality. Haptic technology will be commonly used for computer sex and remote medical examinations. It will become the preferred sexual medium since it is safe and enhances the experience.
