Gold can alredy be synthethised, but either all synthetic gold isotopes are radioactive or you have to use very rare metals (like Pt or Hg196) to obtain stable Au197. To do that you need a particle accelerator or a nuclear reactor, both of which are very expensive. https://en.wikipedia.org/wiki/Synthesis_of_precious_metals#Gold https://en.wikipedia.org/wiki/Synthesis_of_precious_metals#G... The solid gold asteroid crashing onto Eatrh theory is even less plausible. So I'd venture to say gold is a quite safe store of value for the time being. A lot better than Bitcoin or any other crypto currency that could be easily wiped out in the event of a nuclear blast or rendered useless in the absence of electricity.
