I believe that Mankind is Gonna be around for a long long time. The Technological Strives made in the last 100 years pales in Comparison to what we will see in the next 20. Things that seem impossible today will be commonplace tommorow. Personaly I Think mankind will eventually move the entire population to a controlled enviroment like a dyson sphere therby rendering the human race immortal for all intents and purposes.
HEY YOU ASKED
