Change isn't always good but it isn't always bad either.
We don't have Polio or smallpox anymore. Not many Americans die of cholera, yellow fever or malaria. Most people that live far from a city or town can drive there instead of walking or riding a horse. We can travel coast to coast in 5 hours. We can travel to other continents in less than a day. You can send an e-mail, of significant length and with images and videos attached - around the world in seconds, for pennies. We have cell phones that allow instantaneous communication, to an unbelievably large portion of the world. Most of us have access to electricity and clean water.
Yes, the business environment changes. It will ALWAYS change. Retail looks MUCH different than it did even 30 years ago and 30 years from now it will look different than today.
Walk around in any old city or town, especially on the east coast, and look at the history. Most towns had stables to shelter and feed your horse. Big cities had dozens of stables. Those building have been repurposed, probably many times over. Any railroad or port city will have a warehouse district. Goods are now handled in shipping containers and those old warehouses are apartments, storage facilities or some new industry.
Sears was the anchor store in many shopping malls across America. Malls are DEAD. Those buildings and the land they sit on will morph into something else.
Life goes on. Business evolves.
