If you care to check out the link above you just might learn something about the astounding depth of your ignorance concerning gold. What you don't know would fill volumes.
I suppose if you are running a clean-room chip factory in your garage, gold is useful to you.
Gold prices are not running up because of a demand for gold by end-users, they are running up because people want to put coins in their safety deposit boxes in the hope that in a year someone else will want to pay them a lot more to put the coins in THEIR safety deposit boxes.
I don't imagine even the rabid pro-gold posters are going to argue that gold is a good investment because of it's real-world uses. But since I have trouble imagining how people end up being rabid pro-gold posters, I suppose I could be surprised.
Meanwhile, nobody is buying oil to lock it up in their bank so they can sell it later (well, the oil companies do that, and there is a fledgling oil-purchase exchange where people bought gas years ago which was stored for use at a low price later, but even that was so they could USE it later.
How many gold bugs are going to melt down their coins in a couple of years to make rings, or to finish up their communications satellite, or to gold-plate their own monster audio cables or replace all their old silver fillings?
The uses of gold would fit nicely in bullet form on a small-print 9x11 glossy. I'm certain a skilled writer could fit every useful piece of information about gold in a single book.
And being employed at a site that actually HAS cleanroom manufacturing of chips for multiple uses, your lack of knowledge of my knowledge, while not volume-filling, is not something to brag about.
Only said that to suggest that if you are looking to educate someone, it's better to present information in a positive way without including uninformed judgment that might make you look silly.
