No nanobots

No self-replicating ones

This is not about nanobots (especially not the self replicating type).

While self replication nanobots (aka molecular assemblers) where an early idea that naturally suggested itself (it was originally presented in the book "Engines of Creation" 1986) slightly less old (and much less known) methodical work ("Nanosystems" 1992 - same author) strongly points to nanofactories as a much better target.

• The self-replicating molecular assembler concept is outdated.
  It was superseded by Nanofactories since before 1992!

(Details: Molecular assembler)

Associated traits that have nothing to do with advanced productive APM systems:

• swarms
• living & evolving
• insatiable, "metabolize" just about anything -- (see: Omnivorous nanobots)
• super dangerous - the accident is unavoidable and cataclysmic

Few non-self-replicating ones

Non self-replicating medical nanobots, utility fog and similar concepts are still not outdated but:

• As especially difficult to design systems the lie even beyond the far term target of Nanofactories (which are a main focus of this wiki).
• They make up only a very tiny part of the possible product space. Most products will be devices made from arrangements of highly specialized mechanical metamaterials. Just like computers do not consist out of "computronium" advanced products will not consist out of "nanofogonium".
  Advanced products out of complexly intertwined metamaterials rarely (if at all) make it into popular fiction probably because (a) the concept is barely known and (b) it would requires in depth explanations.
