The following argument is philosophical:
In the past, a lot of effort was made to create gold, of course that didn’t work. But now you can transfer cheap material into something that is 150x more expensive than gold. Namely MLCC capacitors in size 008004. The size is just 0.25 x 0.125 x 0.125mm, the weight is 16 micrograms and the price is about $0.1 per piece.
That makes $6000 per gram which is 150 times more expensive than gold. Moreover, a cube of 1cm3 built from these capacitors costs $25000.
(If I've made a mistake, I'd like to hear about it.)
