Future of mankind

What do you think will happen? I think space settlement seems pretty interesting, though I can't really decide on its likelihood. Space settlement, it seems to me, would also cause humanity to branch off into separate species, since the requirements for life in space are different than on Earth.

With growing population and technology, the future's pretty much open for anything, assuming we don't blow ourselves up too soon.

http://future.wikia.org/ is a nice site on this.

The moon could quickly become an industrial resource and from that point on it would pay for itself. On the other hand if we could get some kind of radiation to the point where they can transfer energy at low loss rate we could use orbital facilities to transfer the all but infinite power of our sun into electrical energy and then beam it down in the form of electromagnetic energy.
