Anyways, this overview effect is something I always felt, even without going into space. I always felt we were wasting time with our squabbling over borders down here. I think most scifi geeks feel this way, and I don't mean star trek scifi, I mean Alastair Reynolds, Ian Banks and such.
But the problem is that the solution my mind always reaches for requires autocracy to fix the problems. So in a sense our problems are caused by our desire to be free.
Honestly I don't think most of us are more than trained apes, do we deserve to be free and pollute our earth? I don't want autocracy but I definitely want a lot stronger government to regulate our problems away. Globally.
