keep in mind: 1. 100 years ago, there were only about 1 billion people on earth, today, nearly 7 billion, whether civilization began 20000 years ago or 200 billion years ago. 2. the advancement of technology today relative to 2000 years ago. 3. wars, deaths etc... have increased EXPONENTIALLY. 4. natural disasters, mental illnesses, disease is growing exponentially. that's the question, is the exponent. but even deeper is the exponent against itself. so, when does the exponent end? how close does the asymptote get? how many more years does the earth have relative to these observations? opinion.
