I predict the same (considering VR-type environments). We're already wasting tons of time in artificial social outlets such as Facepalm and Tweeter. Once these become more immersive, it will be even more addicting and capture an even larger percentage of people's attention. It will be like being part of a fantasy movie rather than simply watching one.
...and that's why population growth is going to tank within my lifetime. We're close to developing the technology that will make men (and women too) less interested in putting in the effort required to attract and maintain real relationships. It's already started. Not only that, but the age of marriage has been increasing for both men and women, which ends up reducing the number of children they have.
The US has a negative population growth from a fertility standpoint.
