People are always skeptical of new technology. And not entirely without reason. It's not always clear what the advantages are (early versions of new things sometimes are not actually better than the old thing), or what the cost will be: progress doesn't come for free. In the early days of the Internet, part of the problem was that most people just didn't have a way to access it until there were commercial ISPs, and the Web made it relatively easy to find and share stuff. And of course, new things often come with a lot of hype, that may take a long time to really pan out.

And nowadays we sometimes use the phrase 'the killer appp--the function that clicks with the new technology that drives adoption.
