As usual, Kaku does a wonderful job of causing the listener to think about situations and repercussions that while simple, are often overlooked. The idea that extraterrestrials are likely to be predators is one I've rarely heard, and idea of encryption in an alien message is one that is all too often forgotten.
Definitively a video worth watching.
So what do you think about Kaku's idea of predatory aliens? Do you think an organization would release the information if they were to discover alien life or would they be forced to remain silent? Is it even possible to force somebody to remain silent in this day of near constant internet access?
