Very impressive talk in the last TED. All of history (as we think we know it).

Main points I’ve noticed:

• DNA – learning from errors in its copies!
• In the past 4b years we was it time after time.
• 2b years ago – it started…
• Our language is what gave us our power and our history.
• Collective learning.
• Farming was energy bonanza.
• 7B people are one huge brain today.
• Goldilocks condition are in danger.
• The big history show us the challenges and dangers we are facing
