It's progress. Some of these ideas fade away, some survive, and some prosper. I have an app for umpteen things, which once tried are an incey wincey bit better than the old way, but that's enough to make me keep on using them.
The latest for me is paying for my parking through an app on my phone. Paying at the pay & display machine is a fairly efficient way of doing it, and has prospered for a long time, but I now pay through an app every time I can and even pay 20p for the privilege.
Uber is similar. I'll never pay cash for a taxi again in a town with Uber, but paying the drive with cash has stood the test of time until now.
