I believe the greatest improvements will be in the curing of all known diseases in the present day. I envision vast advances in medicine and technology, where the average life expectancy will be well over 100 years. There will also be means to feed the world via plant and animal cloning. No one should go hungry. The planet will be self-sufficient. Oil will no longer exist. There will be new technologies that will be derived from hydrogen and solar energies. There will be mass transit systems that will eliminate the use of personal vehicles. Automobiles as we know it now will be totally revamped as they are beginning to face that prospect now. The planet will be much cleaner. Wars will be diminished because we will become void of nuclear arms. There will be new weaponry that will eliminate nukes and render them useless. Most wars that were begun because one nation lacked a resource, say oil, will end because the uses will end. The only issue we will have is over-population because of the health industry and increase in life's years. By 2109, perhaps some may live on Mars or another distant planet.
