Nanotechnology will become first nature to us

Technology becomes indeed invisible, but that's also the point. Because good technology always becomes invisible. You just mentioned nanotechnology everywhere on the sidewalks, but if you think of the sidewalks, in a way they already are a technology in themselves. But they're a technology that functions well, and every technology that functions well becomes invisible. So there's nothing wrong with that. In a sense, if you look at something a long time ago, for instance, agriculture, that was developed ten thousand years ago, and back then it was a radical new technology. It was a radical new idea to place crops in a row and wait until they grow and then harvest them. That was really something different from just being part of nature and trying to get your food. So back then it was a new emerging technology, and I guess people also worried about the dangers and the risks and the opportunities. But right now we don't see it as technology anymore. It has become invisible. It functions, we're aware that it's there, and it's part of our lives. It's not even a second nature. One could say it became our first nature. We cannot imagine life anymore without agriculture. It's just not an option. And presumably the same will happen over time with technologies that are emerging now, like nanotechnologies or digital information technologies, that they are introduced in our lives and we think of them and we see them as something new, but over time we get used to them, and perhaps the next generation will perceive them as something completely natural that's just out there and it's invisible and they will not describe it as technology.
