That article you have linked is a crystalised instance of human stupidity and a demonstration of how far down it can go WRT the level of intelligence. An idiot that thinks he can connect stupidity and intelligence to genetics without demonstrating the truth of such claim in any way, acceptable or not. One can do nothing but hope all of that article is a joke.

edit: I can't sleep if I don't mention that that entire harmful.cat-v.org site is a fractal of stupidity, so it's no surprise that such article appears there. They hiss at all the software out there that has made a nearly completely free computing system possible, and the alternative they propose is an operating system that died some decades ago and compilers that can't compile standards-compliant C code. Go and Limbo as an alternative to Python and Ruby? Really? Where's Django? Matplotlib? Good morning, people have other things to do than reinventing the wheel every other day.
