Is this by design?
I had this strange thought today about why civilizations seem to rise, advance and eventually destroy themselves. Imagine creation has a finite amount of resources and time. If you wanted those resources to produce the greatest possible variety of outcomes, perhaps having one civilization arise and eventually occupy everything forever wouldn't achieve that. Instead, civilizations could have an inherent tendency toward self-destruction. One rises, develops knowledge and technology, reaches enormous complexity and power, eventually collapses, and makes room for something else to arise. Each civilization becomes almost another iteration of what intelligent life can become. The self-destruct wouldn't necessarily be some literal timer built into creation. It could simply be a consequence of intelligence itself. As intelligence increases, technological power increases. Greater power creates greater complexity and also greater ability to cause catastrophic damage. Eventually a civiliz...
