From Next Big Future: "The [SENS5] conference itself was high quality - many of the scientists that I describe in my book, 100+, were there. Hearing about the tangible progress that these researchers are continually making was very exciting. I noticed that there were many companies that attended this conference, which is an indication that extending health span is a prospect which is starting to garner serious consideration. ... There are a large and growing number of corporations which, although not explicitly focused on anti-aging, are developing treatments and drugs related to longevity. Gene therapy and personalized medicine are the future, and these companies know that. ... The field of regenerative medicine is getting substantial resources. That includes tissue engineering, which is essentially growing organs. The recent successes with growing and implanting human tracheas are exciting. ... The most common concern is that increased life spans will lead to overpopulation. This fear rests on the false Malthusian idea that population grows faster than our ability to provide for ourselves. We haven't run out of resources as population has grown because humans are a resource themselves, providing problem-solving ideas. Also, fertility and world population growth rates are on the decline. ... Perceptions [of longevity science] have changed. The term health extension is actually less controversial than life extension, since everyone wants robust health. There is little resistance to treatments designed to keep people healthy."
