I grew up in Germany in the 80s and everyone was still talking about the gold standard and how the Deutschmark could be strengthened and the importance of the Bundesbank gold reserves.

Gold is still something central bankers think about a lot, and they still buy and buy and buy it. They're steadily repatriating it, on the down-low.

There actually is no evidence that, for instance, the ECB governors actually think their fiat is going to last forever, despite all the CBDC posturing (which seems to largely be a response to the digital yuan and Fedcoin and etc.). They're quietly stocking up gold reserves and trying to balance the per-capita amounts among the various member banks.
