Carl Sagan's words keep going strong and will echo far into the future.
I remember the 80's and how technology was evolving so fast that we thought by the year 2000 or maybe 2010 we would have invented a way to live forever and we would embark on journeys out into space and start new exciting civilizations.
The year 2010 came and what did we get? Pathological ideologies that polarize us and hinder our advancements... Some few are going strong but imagine what we could do without corny ideologies that takes us backwards...
Great video btw.
