Technology is infiltrating deep into our daily lives. It has rendered many things less necessary than they used to be.

Land-line phones are one example. With a cellphone in nearly everyone’s pocket, that old-fashioned cordless is a lot less crucial. Email has eradicated the need for a postage stamp when corresponding.

Even some buildings are becoming less necessary. A lot of people now work from home instead of at an office, connected wirelessly to their coworkers. Others get degrees through the Internet, never setting foot in a classroom.
