To solve difficult problems like this, we really need to game problems to get more people involved. To get a man on the moon, for example, it took almost a decade, billions of dollars, and 300,000 Americans working on it. The problem he wants to solve is even more difficult.
Apollo was a difficult but reasonably straightforward engineering problem, which made it extremely susceptible to having money and manpower thrown at it. Life extension, and even most more modest medical problems, still lack large areas of basic understanding which makes them much less vulnerable to such mass attacks.
