First, we should seriously worry about which aspects of our modern civilization system are rotting. Human culture has lasted a million years, but many parts of our modern world are far younger. If the first easiest version of a system that we can find to do something is typically be a rotting system, and if it takes a lots more work to find a non-rotting version, should we presume that most of the new systems we have are rotting versions? Farming-era empires consistently rotted; how sure can we be that our world-wide industry-era empire isn’t similarly rotting today? We may be accumulating a technical debt that will be expensive to repay.
