The problem with the human body is that it's really
only designed to last us until we breed - 20 years or
so. After that, it starts to fall apart, the
probability of death per unit time doubling every 8
years after you turn 20.

I think I now understand all the fundamental
principles required for FAI. I see how to do it.
Give me 30 years to develop the fundamentals into a
rigorous formal theory (ie. work out the maths) and I
think I could probably do FAI myself. So there's a
much stronger theoretical foundation for AI now.

Another reason I think AI is the better prospect is
because of the tremendous complexity of the human
body. It is reasonable to expect that the
bio-medical route should be able to achieve modest
gains in life-spans, but probably no more an extra
20-40 years on average: "As gerontologists are fond
of pointing out, you could solve all the major
age-related diseases, and you’d still add only about
15 or 20 years to our current average life span of
nearly 80." You wouldn't be able to push life-span
beyond 120 without making really big changes to the
entire human body system.

So the bio-medical route is at best a stop-gap until
FAI. Nano-medical might be able to get better gains,
but nano-tech really needs FAI to be able to control
safely. Only AI would be smart enough to get a handle
on the problem and make truly substantial gains in
