[extropy-chat] self replicating machine ....

[Jan Gruber]

I love the idea of using printers - especially because one could at least do a simple "proof of principle" experiment - maybe not for the self replication part but at least for the "printed" circuit .... Even a simple adder / subtractor circuit printed using a modified inkjet printer would be interesting.

 

But then it looks like that has already been done:

Any idea how complex/big the Epson setup is ?

	The problem is, using already-existing stuff means you don't have to
	make (potentially wildly inaccurate and proof-defeating) guesses.
	
	So, I'd suggest sticking to things that do exist.  Designing self-rep
	by some - any - means is hard enough, without restricting yourself to
	novel means.
