I am also intrigued by silver @Hands - however I only have limited exposure to silver via ownership of South32 (S32) shares. South32 own the Cannington mine in North West Queensland, one of the world's largest producers of silver and lead (and Cannington also produces zinc).

I do think that gold and silver have decoupled now. There used to be like a tether that dragged silver up when gold went up, and dragged silver down when the gold price fell for decent periods of time, but while they still often do move up and down at the same time, the ratio has broken down in recent years, so the moves that silver makes seem to have less to do with gold and the "store of wealth" argument, and more to do with silver's industrial uses.

Gold has far less industrial uses than silver.
That's based on 2020 but I don't think the uses for gold and silver have changed materially since then.
So my observations are that the drivers behind the silver price have changed by more than the drivers behind the gold price have over recent decades, and that has caused a sort-of uncoupling of the two prices, which used to have a fairly reliable relationship to each other, but now - not so much.

In light of that, I don't think investing in silver has the same arguments as investing in gold, and I mean that in terms of both owning physical gold/silver and/or having exposure to one/both of them via ETFs and/or companies that own deposits and produce and sell those metals (i.e. buying shares in gold and/or silver producing companies).
I'm not saying one is better than the other, just that there are different reasons to invest in the two precious metals, and a different set of reasons again for investing in platinum or palladium. And different again for diamonds. All have industrial uses, but I would imagine that none are held purely for investment (or "speculative" purposes) as much as gold is.
Here are the latest charts for both gold and silver in US$ for the past 5 years:

Gold has clearly outperformed over the past 5 years, as it started at a lower point and finished at a higher point relative to silver. Gold has also exhibited less price volatility than silver over the 5 years.
But silver has certainly outperformed over some other timeframes. I think the charts we were looking at over in the gold thread only went up to the end of 2020, or thereabouts, because they were from an article published at that time, and the charts above are current as of today (Wednesday 11th May 2022).
