This is a video where Terrence McKenna talks about various subjects such as how the organism "earth" has evolved and how this evolution is very much exponential - the computer age and computer networking is another tipping point in time.
Terrence McKenna died in year 2000. His theories are amazing and he is a master of language to lay down these theories in an understandable kind of way.
Just give it a watch guys!
And have a good day
