Next fifty years, the work environment will definitely change. People do their own business that can be anywhere. I imagine that which will no more CBD places, staff won't come to work place. People can have a meeting on the Internet, they also can trade and sociality with business partners. You do not see each other, but you can deal with business partner that is really amazing. If do some heavy work, we can use machines or robots. Poeple do not need do it by themselves, so nobody will be hurt and do not happen accident. This is really advantage. The number of vehicle will drop down. The pollution also will decreased that is what I really want to see.
