"We are all interested in the future, for it is where we shall spend the rest of our lives" - Criswell, in Plan Nine From Outer Space.
I once had a copy of The Book of Predictions, a collection of ideas of what the future holds. The predictions were mostly from experts in various fields and people like SF writers whose professions involve speculations about upcoming events. Towards the back there were also predictions from psychics; these proved to be the least accurate guesses of all.
Below you shall find some of my guesses at the future. I'll note afterwards in parenthesis a level of likelihood. I may add other people's predictions if I find them interesting.
1. The first successful commercial sales of androids (human looking robots) will be as "companions"; actually full function sex robots. ( almost certain )
2. The Social Security crisis we hear about will end up not being much of a problem. Not because our wonderful Congresscreatures will come up with a brilliant solution, but because physical aging will be eliminated for almost everyone before the later "baby boomers" are eligible. When a person of 80 is physically the equivalent of someone who is 20, it will not make sense to have a government retirement program anymore. ( almost certain )
3. Barring radical reductions in the cost of launch vehicles, we won't see private enterprise making the initial investments to colonise space. The profits will take too long to achieve. It will take some form of government assistance or credits or initial colony establishment for humanity to become a species that lives off the Earth as well as on it. ( fairly sure )
4. On the other hand, once we have the first colonies and mines and production facilities we'll have a viable off Earth civilization that needs not Earth resources in less than 100 years. ( almost certain )
5. It will be possible to transfer a person's consciousness into some form of computer. This will become standard practice for people who are dying. ( 50-50 )
6. The existence of something that survives death, a "soul" or "spirit" will be proven. The exact nature of the "afterlife" will not be known however, and it will do nothing to prove the existence of God or gods. ( 50-50; could be said to be wishful thinking )
7. A human being will be cloned before 2005, maybe even before 2000. ( fairly sure )
8. A Neanderthal will be cloned. ( fairly sure )
9. Some idealistic women will volunteer to be surrogate mothers of rare apes as the populations of gorillas and bonobos are reduced in the wild. ( fairly sure; it should be physically possible, I think )
10. A "minor" nuclear exchange will lead to some form of world government. ( 50-50 )
More predictions to come.
