This is going to sound stupid but I like using hyper rationalism to solve, or answer questions such as these. The real question would be Is this game going to adapt so people no longer spend time doing other things, such as dating, forming relationships with other people (In a face to face environment) and going to work, school etc. These things are already happening. Many of us spend time playing because we prefer it to reading, going outside etc. So in a sense have we not already reached the point in which the question suggests?
