Movement creates certain efficiencies because it effectively eliminates friction. Sharp points may be smoothed down, or you may realize that you can get away with using less. When you are in constant motion, you tend to realize what you really need and may even start discarding things along the way.
Getting to the essence of an idea, concept, or even yourself is a matter of stripping away until all that remains is what you really need--and no more.
What is the future of mobility?
It's hard to say exactly, but the general idea that people will be doing more with less. They will be able to reach farther with less movement, coordinate more with less contact, and see more with less experience. The key with this line of thinking is that there must be balance.
