Cyber sex will be happening big time. You'll be able to jack into a pre-recorded, interactive cybersex session with any of your choice of cyber sex stars of the day. All you'll need is plenty of cyber money. Now jump ahead a few more years. Humanity is dying out.
World population is down to a few billion or so.
Nobody has any need to travel anywhere anymore. Humans aren't reproducing because they never meet anybody to reproduce with - they never go anywhere and cyber sex satisfies most reproduction 'urges'. A gleam in daddy's eye leads only to a session with the ThrustMaster, a huge cyber bill, and no offspring. People get out of the habit of meeting other people in the flesh and feel uncomfortable in the presence of live humans. Robots satisfy most physical needs.
