Where will technology be in 1, 5, 10, 100, 10^3, 10^4 years?
Areas to consider:
* Locomotion
* Communication
* Agriculture/energy
* Infrastructure and social arrangements
As technologists, what are your thoughts on this?
I think Maslow's hierarchy of needs might help define the priority of invention (http://en.wikipedia.org/wiki/Maslows_hierarchy_of_needs).
The ultimate step in this hierarchy is "self-actualization", whatever that is. Once we satisfy our social, biological needs, (easy cheap food, plentiful resources) we can work on technology to "self-actualize". This technology and process could fundamentally change the meaning of being human.
Where's entertainment in that hierarchy of needs?
Maybe entertainment isn't a need, but it's a pretty strong want, a want that has resulted in considerable invention already.
In the 20-30 year time frame everything from immortality to artificial sentience could be possible.
Although I don't believe it is fully impossible to predict where we will be 20 years from now -- it's just an ability that's historically limited to a few people by the role they have in the process.
