It is the nature of intelligent life to destroy itself?

Here's something amusing - and sad.

So under Fermi paradox, intelligent life is meant to self-destruct due to an unstable system (i.e. we create robots which takes jobs away from humans, thus a rising homeless population. Too many people on Welfare and the government goes broke, or worse we have the French Revolution all over again) or due to our own aggressive, consuming ways.

We are doomed. Although it may not be a permanent doom, as the article states:

This argument does not require the civilization to entirely self-destruct, only to become once again non-technological. In other ways it could persist and even thrive according to evolutionary standards, which postulate producing offspring as the sole goal of life — not "progress", be it in terms of technology or even intelligence.

Does the Dark Ages after the fall of the Roman Empire ring a bell? I don't know about you but I'm going to start building that rocket to Mars.
