I think if you look at the many expressions of violence in our society-- war being one of those that keeps happening-- you really don't need to know how to read minds to know what others are thinking. And you certainly don't need to read minds to know what holywood will do next. Also, there are a lot of folks that know their spiritual beliefs are built on a foundation of jello; however, they go to church or worship in groups nonetheless. Do people care about the truth? Do they value it? In reality finding a God fearing man who won't beat you when you burn dinner is more valuable than the truth.
I think what you're talking about is a better connection between minds. That is if we could read minds, you would be better connected to your fellow man-- too connected perhaps. What would happen when morally good dumb minds are connected to smart evil ones. Will the dumb minds be outraged, enlightened or dissapointed? Will the smart minds gain empathy, be dumbed down or become more evil? What is the worth of enlightened dumb minds? What is the worth of an evil mind that understands more? I think the potential for chaos is there; but also, the potential for harmony is there. Oh well, let's face it-- it ain't going to happen.
