I heard a quote that said "Businesses don't run out of money, they run out of ideas." We've solved a lot of the most difficult problems of the last centuries (mass production, improved quality, communication technology) and we're wondering what's left.

Does anyone feel like they have an idea of what the future will look like 10 years?
