Bill gates Ted talk ..what is he saying? Fact check the fact checkers

Not only did he say what he allegedly never said according to some fact checking entities that have been popping up recently on most big social media platforms; he has a whole equation for what needs to happen! He also cracks a little joke, about which variable should be brought all the way down to zero which is funny because one of the variables include; you , I, your neighbour, your aunt and so on.
