A couple of weeks ago I said it makes sense to be skeptical and critical of new technologies, especially when they are made by big people, and was criticized for this. I think you hit the nail on the head. The problem is that technology is not only what it is, per se, but also what we want it to be. So people want to believe, much more than they actually need the thing in practice. And the people who build the technology are aware of this, and make use of it for their benefit. In some instances, the market is far from being a competition based only on skills and product quality. There is a lot of fantasy, too.
