Very philosophical take on things.

> There are no immovable mountain. Everything is vulnerable, everything exists because it, or something esle, didn't break/transform it into something else.

Vulnerability is what humans would use do describe how something alive and conceptually "whole". It is something can can be exploited to inverse those properties. If we are all just matter in different configurations, in a universe full of matter in infinite combinations, "vulnerable" loses its meaning.

So perhaps, in the larger scale of things, nothing is truly vulnerable.
