What do you mean by far future ? 2100AD ? 2500AD ? 5000AD ? Later ?

A few ideas and possible scenarios:

* the human race is still more likely to wipe itself out then not. We have nukes, we're building a better bomb, we've got bio weapons and chemical weapons, we've got a lot of lunatics.

*If we look at histrory civilization seems to be moving towards a more libertarian society. From strict adherence to elders, medicine men, and rules of the group to universal slavery under a God-King, to fuedalism to aristocratic factory owners to democratic freedom... (vast simplification of history of course). We'll probably continue for a while to a more 'open' and 'free' society, whatever that will mean.

*corporations taking over is an interesting idea, it's a possibility, but i don't see that as a long term stable form of society.

* I think the ideal that we'll ever going to be completely peaceful (incl no crime) is probably never achievable, we're not wired that way.

* ...unless we change the wiring. Brave New World mentions the potential of specially bred workers and scientists and other classes. Eugenetics used to be popular, the idea of class or caste systems seems quite popular from time to time. Messing with genetics might change society in a BIG way. The idea that we'll all just be smarter, fitter, healthier and happier seems too optimistic to me, I suspect we might create a subclass of humans at some point, unless we can let the robots do it for us (NOTE: robot originally referred to human serfs, the word was first introduced in some 19th century sci fi book if I remember my wiki...)

* Robots ! Will we ever be able to create androids ? Machines that have equal intelligence as humans ? Superior intelligence perhaps ? Personally I think we're far removed from ever creating an artificial 'soul'. But someone might figure it out some day. I think such a discovery would completely change the world in a couple of years.

* the metaverse/Matrix/second life/internets. Hard to say what that will evolve into. It's hard to picture a future world were the 'virtual' world is unimportant though.

* Cybernetcs, cyborgs, mind to machine transplants. Kurzweil has some interesting ideas about how humans will evolve in the future, essentially, we'll all become cyborgs living more in a vuirtual world than in reality, and we'll be virtually immortal. Miniturization tech is getting more and more advanced, neurology is a very popular science nowadays, and we're always looking for ways to extend out lifetime. Who knows what will happen ?

*Space travel: unlikely to become really big unless we get a really good reason to go out there (resources or fleeing earth)
