              4:36 This will be our undoing in the future. Ultimately, a mad company will develop a neural network as complex as the stars in the universe with the abilities as threatening as it can be.

              And this my friend will be our undoing!!

                              What if a sentient ai is created? If its creating infidente random connections then at one point theres a bot that relises its a bot made to work... Or they do but dont care becose he wants to... Yknow, be a algorithm... But what if... Yknow nebermins

                                    This video is actually one of my favorite on youtube. I just remembered about it today and had to go through my "Favourites" playlist just to find it. This is wonderfully explained, I still don't understand how I didn't subscribe to you after watching this video. But now I have.

                                                So, this was fascinating but this does leave me worried. Actually made a short video on it just now in response to this one. Maybe someone smarter than me can put my worry about the possible danger of this to rest?

                                                          I like how at the end of video, even Grey acknowledge the bots, and bow to the bots in a comical yet self loathing way to promote his videos and channel (somewhat unwillingly).

I've learned so much stuff since watching this and I just want to thank you, CGP Grey. In fact, this video basically picked my career choice for me. It's so amazingly made, and I just want to thank you for making this.
