One I think they're missing (though perhaps implicit in a couple of the others) is "People are skeptical of new things that promise a lot." Many new technologies have been oversold by the media and... salespeople, leading people over time to generally be skeptical that a really new technology can actually do all the things it promises. As a result, it takes time to convince people that, for example, the dish washer really is better than washing dishes yourself and not just a gimmick to take more money out of your wallet.

In many cases, this skepticism is healthy because (as the article mentions in the beginning), a lot of new tech is not actually ready for primetime for quite some time after it is invented.
