RE: [CAD_CAM_EDM_DRO] Re: Soliciting Feedback: OS Design

Your logic law concern is accurate only if you can't describe pieces
algorithmically, and have to instead describe them atom by atom or molecule
by molecule. If you can describe pieces as algorithms or other higher-order
geometry (or toolpaths) or copied pieces (think cells) then replication is
quite possible.

This topic will quickly be ruled "OT" so I'll get in quick to beat
the gun.:-)

What you are looking to do almost fits in the "perpetual motion
machine" round-bin. Almost.

It violates some basic laws of logic and a whole bunch of economic
ones.

Logic law: A system can never be completely self-aware. The volume of
information data to completely describe any system has to exceed the
system itself. It's a never-ending and growing circle if you add that
self-description data to the system. You do, the system gets bigger
and the data to describe the added self-description grows as well.
Around and around.

Economic laws: So let's say you overcome the above. Some parts of the
self-replicator are made of tool-steel and aluminum, other parts are
made of silicon, copper foil and fiberglass-epoxy.

Objection 1: You have to purchase the diverse raw materials your self-
replicator needs to self-replicate. Some of these materials are of a
special and rare nature. Will you pay significantly less for them
than you you would for the fabricated replacement part?

Objection 2: You pay for a specific function from a mechanism. A
router does a truly crappy job milling tool-steel and a mill suitable
for milling tool-steel makes for a really poor 4' by 8' wood router.
Let's not even touch the pick-and-place function, board etching and
drilling and reflow oven functions to self-replicate electronics. How
much would this "Swiss-knife" machine cost versus one meant for the
task at hand; route wood, mill steel or SMT-mount PCBs?

Objection 3: You don't have a self-replicator turning out copies of
itself when things are going well. You need a copy when the original
breaks. When it's broken, how is it going to turn out a copy of
itself?

About ideas and names: Naming things is the easiest task. For that
reason it should reserved for after you have done the hard work of
actually building your idea and having a working version. Name it
after the work is done, not before. That's good form.
