Human beings are known for inventing things that they had never really needed.
Or, to be more specific, that they believed they needed until they actually invented it, which was the exact moment when they saw they didn't.
Sometimes, the new invention just keeps existing, and so do us.
But there are these rare, particular occasions in which things go a little bit wrong and the invention just can't keep existing.
And there are these rarer, even more particular occasions in which things go abnormally wrong and the invention keeps existing, but we run the risk of irremediably ceasing to exist.
