I would expect a lot of changes. I expect a very great population in the future ( as expected).I suspect that aircraft in space would be commercialized,people would ride on it as normal like airplanes. There might be a new invention greater than internet.Internet might be use for communication like normal telephone companies.Telephone companies woud be lessen like the booming of cellular phones.Home studies and online teachings would be boosted than today.What comes into your mind?
