Ray Kurzweil is well know due to his inventions, his famous book The Singularity Is Near: When Humans Transcend Biology, and his ingestion of hundreds of multivitamins in an effort to prolong his life (end goal = live forever).  Many are turned off by such goals in a world where so many live in abject poverty.  In any event, Kurzweil’s recent CNN article is a must read.  The ongoing and coming rapid advances in biology are very relevant to the hair loss world:

In 2008, I attended the Singularity Summit in San Jose and got a chance to talk with Kurzweil in an informal group setting.  Ever since, I have always been keen to read anything new by him.  I am not sure what to make of his prognostications, but it is great to have optimistic super intelligent people like him and Dr. Michio Kaku (Physics of the Future: How Science Will Shape Human Destiny and Our Daily Lives by the Year 2100) in an age of too much fear mongering and conspiracy theories.
