- At least in this last application, the gold is recoverable. In
- fact, there are companies in operation today whose sole purpose is to
- recover gold from circuit boards. I will certainly agree that, due to
- human superstition, it's not likely we'll be recovering gold from
- graveyards anytime soon. However, you shouldn't underestimate our
- ability to get around difficult extractive problems when necessary: If
- ever we needed it again, we would find a way to get it out of catalytic
- converters.
- These observations are however not the reason I am posting. I would
- like to know if anyone else thinks that Rajat's posting is silly. (I
- tried to find a more tactful term, but I couldn't.) First of all, I
- haven't heard that there is anything even remotely resembling a gold
- supply crisis. Secondly, gold makes pretty jewelry, but so what? I
- would rather have it play a useful technological role than see it wind
- up as a useless ornament. Am I the only one with this sort of opinion?
