- You seem to forget another point; even an immature nanotechnology will
- likely radically alter our lifespans.
-
- And for those of us who don't like the idea of being caught dying just
- a few decades away from nanotechnology, there is always cryonics...

- Given the fact that you can construct more assemblers with self
- reproduction, why should we be restricted to so few assemblers?

- Things have changed a lot since Nylon was designed 50 years ago. Now
- we have computers to help us with our R&D. We also have several
- interesting synergies: faster computers mean faster/better R&D.
- Faster/better R&D means faster computers. Crude assemblers allow us to
- build yet faster computers and yet better assemblers simulated with
- those faster computers. Technologies like this don't advance linearly;
- they advance exponentially in early stages. I'd say you are being
- radically pessimistic. Although I can see reasonable arguments for
- nanotechnology taking another 50 years to develop (I don't agree, but
- I can see the arguments), I don't see how once we have nanotechnology
- the advances after that won't proceed at an unimaginably fast rate as
- the design and production tools we use themselves improve radically,
- and continue to improve radically because we can use the tools to
- design better tools, and so forth.
