When we do finally reach the point where everybody has those wearables, a very strange phenomenon will occur. Some people will start to post their life stream as a matter of course, and other people will start to become addicted to the moment by moment experience of being somebody else.
For some people with weak egos, this will result in a loosening of the sense of identity itself. Rather than being themselves, they will start to have the illusion of being somebody else.
I do not think that this will be a good thing.
Cue “Being John Malkovich”.
