The applications and importance has been discussed, but let me explain why what we are doing right now does not work which will also emphasize the importance of this.

At this time, we create drugs, test them on animals, and see what the side effects and results actually are. We are very limited in our capabilities and basically throw mud at the wall and see what sticks. This would allow us to try potential drug candidates without so much randomness.
