    and rolls of charts, often with mistakes and guesswork, around the late 1400s.  I suspect that you would agree that technology for determining your current location has improved.

    While 3-D manufacturing right here and now may not make a shoe, give it a year or three, and it will.

    NASA had (last time I checked was 2 yrs ago) a very talented blacksmith on its staff. I know, because he taught me some techniques on toolmaking and treatment of metal, such as hardening it without causing it to be brittle). He was a great guy - a metallurgist PhD, who kept an anvil, a coal forge, and a gas forge in his lab. Man, could he smith. What a talent. What a warped sense of humor, too.

    HIs key job? The engines powering the lift-off of the space shuttle had a complex titanium part that they could not manufacture properly in a factory. Instead, they relied on him to hand fashion the part for each engine, and for each test firing. That's right, one of the most modern and powerful engines relying on the second oldest profession  to work.

    Because that engine design was so robust and effective, I suspect that it will be used in future craft for some time to come. BUT, Nasa did announce that certain parts for that engine will now be manufactured by 3-d technology, using titanium.  

    My point is, his job is about to be replaced with a 3-d machine, a technology that currently mimics an iron needle in a bowl of water, trying to point north.

    What we call god is merely a living creature with superior technology & understanding. If their fragile egos demand prayer, they lose that superiority.
