Queue Lines
Many companies have already implemented an "online" line system, where an operator will simply call back when the person has moved to the front of the queue. It's likely that physical lines will soon be a thing of the past. Technology that automatically charges credit cards when we leave a store would be a time-saving invention.
Printed Books
Thanks to the invention of the eBook and eReaders, print books might be on their way out within the next few years. Not only would it be environmentally friendly to save the paper books are printed on, but it would be a more convenient way to access libraries. However, nobody wants to see the closure of real libraries.
