I'm going to preface this with a statement that I was a PM holder before a Bitcoiner. I still have significant investment in PMs. I have no plans to divest such. That said...
Gold is the supreme hedge against the total collapse of all industry and technology. It is an asset that will assuredly retain its value a thousand years from now, or in ten thousand years, or longerif humans still exist.
While I think the chance of this staying true at least for my lifetime* is better than 50-50, I'm not so sanguine about gold's longer-term prospects. What exactly makes you so sure of such?
