This particular Ted Talk by Sal Kan discuses the potential of a implementing a new style of learning techniques, and how our current system is primal in its ways.

This could be very beneficial to human nature by showing student and people that the majority of people are capable of learning, what we consider difficult subjects. Not all students learn and think at the same pace, and by building an education system that fits these needs could

Betzig won a noble piece prize for his work, because now scientific can see things in cells we have never seen before. Because of this development Haseltine thinks we can look into cells and see what causes some of them to have immortality. Dr. Gray is looking into using viruses as a sort of gene therapy to help rejuvenate our cells thanks to Betzig’s microscope. So, Heseltine believes the next big breakthrough could possibly be and immortal human. When looking at ecological sustainability this breakthrough could be very damaging to our environment. Due to limited resources, if humans were to become immortal we would exponentially grow at rates never conceived before and then begin to decline rapidly. Although this would be a major breakthrough, I believe it would do more harm than good to our society and the preservation of the human
