Thank you for that information.
I strongly agree that we are seemingly in a cyclic vortex of development and destruction, yet I remain confident that ultimately madmen willing to burn it all down will eventually fail to do so, and the abilities native to humanity via the agency of physics will end that cycle forever.
Either that, or we will become extinct, which is not a factor in anyone's calculations, since that result makes every calculation moot. I therefore ignore that possibility.
