Your response is rude, but more important you seem to ignore what I've
written.  Check out below.

No.  Who says they can't be "locally replicated" -- your use
of "replication" here is totally bogus.  Your use of "locally" means you
didn't read -- or understand -- what I wrote.  I'm talking about a
self-replicating machine system HERE ON EARTH with humans at beck and call,
as contrasted with the MORE DIFFICULT moon-based operation of AASM.

What are you talking about here?  Have you read AASM?  There's no indication
here that you have, or that if you have you understand what you read.  Talk
about hand-waving.  It makes me think it's not even worth respondoing to
someone so dishonest in discussion.

That said.... Any project that is to be completed must have sufficient
resources,...well duh.  And the resources required are easily with human
reach.  For example a very small fraction of what's been spent on the Iraq
war.  Do you know what that cost was estimated to be by Freitas in AASM?  If
you did you would not question the sufficiency of resources.

Current industrial infrastructure has sufficient everything to do what it
does, else it wouldn't successfully complete anything.

What large numbers of humans in what hostile environment?  What in the world
are you talking about.  You're certainly not talking about what I'm talking
about.  Reducing the human factor in a Self-replicating Machine System
(SRMS) means NOT having large numbers of humans participating anywhere.
Small numbers, yes, for maintenance and troubleshooting in the early
prototyping and shakedown stages.  But
