The beginnings of some sort of Sensory Deprivation Pod or Suit, that shuts out all external stimuli but can deliver controlled tactile experiences to work in conjunction with (By Then) Refined V.R. technology. Basically, it will enable you to touch and interact with a virtual world creating total immersion, like a wearable holodeck. You can touch what you want, bang what you want, and your V.R. service provider will be able to track all of it and build a profile on you. Human Birth's will plummet even more so in first world countries. Marriage may become an antiquated concept. Once the technology is refined people will begin to spend the majority of their free time not working or sleeping in virtual worlds, preferring to live in a fantasy land as opposed to real life. Physical possessions will become less relevant, as people will prefer virtual goods. Of course you'll need to eat, use the restroom, etc. still but you get the idea.
