I'll create here are a list of talks that I think everyone should watch. Everyone in a while I'll add another one.
The Internet is My Religion - Jim Gilliam
A powerful talk that shows how connectivity can change the life of people.
Bobby McFerrin Demonstrates the Power of the Pentatonic Scale
The previous talk is a bit heavy, so here is Bobby McFerrin in another "talk" that deals with some kind of "Hacking of the mind". McFerrin is obviously well known for his song - Don't worry, Be happy. In case you haven't noticed, the song has not musical instruments. It's made only of vocals. I love this video because it relates to cyber security in many ways and especially in the fact that people's mind, everywhere, works in the same way.
