Alternate pathways to assemblers?

from the Many-roads dept.
SteveLenhert at About.com writes of an item posted there that looks at an alternate approach to developing an assembler:"This essay ("Are you a Self-Assembler?") discusses an approach towards molecular nanotechnology that does not require self-replicating assemblers and can be realized using available biotechnology."

There is a related item on the site that addresses some of the same issues.
