What bugs me is that it seems like the fact of some people being more intelligent than others is denied, at least in America. I don't like it when parents tell their low IQ children that they could pursue any career that they want, when in reality they can't. Someone with an IQ of 70 ain't going to become a theoretical physicist. While IQ tests are not perfect, they still are pretty good at gauging general intelligence, provided the test is given properly, and the person being tested tries their hardest on the test.
I see it as follows.
1. Man creates technology
2. Man evolves technology
3. Mankind starts using it and evolves
4. Man teeters on the edge between too much dependence
5. Man pushes past that
6. Man goes to war against itself and loses plunging into stone age (bit of a hyperbole but you get what I mean)
Are you familiar with the philosophical concept of a great filter as a solution to the Fermi paradox? I think that technology could be the great filter. We fail to realize that problems, such as climate change, are caused purely by human created technology, so we seek technological solutions to problems created by technology, it's stupendously counterintuitive.
