Targetted Cancer Therapy Medicine - PLX4032

Just read a report about PLX4032.

I was against any gene based medications. However, watching people to have their second chance of life is really encouraging. It is so encouraging that most of us forgets the side effects we may face in the future and the backfire from the nature.

I have a few unanswered questions:

1. If one day a medicine was invented to revert aging and subsequently keeping people alive forever, what would the consequence be?
2. As all other technologies human developed in the history, powerful technology *will* be misused at some point in time. For example, due to the justified development for medication, the maturing gene based technologies can be used to create super solders, superman (and if superman becomes a super stucker..). How do we prevent that?
3. The evolution involves adapting to ever changing climate, environment, threats, and so on. With gene medications, will it become that human become un-adaptive in the end?

The attractiveness of PLX4032 is infinite to those who needs it. History suggests it is impossible to stop it in a capitalism market. So maybe we should try to define the boundary of gene based technologies?!
