I think that one of the primary reasons things have stalled is the fear we all carry around because we don't have any decent operating systems. With MS-DOS you could copy the OS disk, write protect it... load up any random piece of shareware and just try it out. There was zero chance it would toast anything, and you might find a gem.

We don't click on links that go to web sites we don't trust. We don't open email attachments, we're paranoid... because our operating systems weren't designed for the age of the internet.
