Collapsed Anthill

Last summer I observed a bustling ant colony with an impressive anthill. This year at this place I found a hole filled with soft debris. The colony was gone, and the convexity transformed into a concavity.

What can teach this little story?

1. Anthills although rising well above the ground contain many cavities that collapse when the framework that keeps them open is not maintained.
2. Every fauceir has its limited life span. That applies to social fauceirs too.

The latter, by the way, also claims a book that I recently started to read[Error: Wrong macro arguments: "4490" for macro 'ref' (maybe wrong macro tag syntax?)] . Sorry only German. The title is "Intelligence and its enemies - The failure of modern societies to keep their intelligent people thriving"
