Nonsense. Gold has many uses other then used as currency or for speculation.
If you account for the damage to the environment mining gold causes its value is actually negative
I don't think you appreciate the use of gold. For one, every chip is using it. Would we better off without semiconductors in exchange for a few less mercury ponds?
You keep missing the point.
I wonder if gold being useful in semiconductor design influenced the Greeks in adopting it as a currency. Maybe they just used it because it was portable, fungible, and scarce?
