today I learned that we (as a civilization) now can put 16 silicon flash dice into a single 700µm microSD card on a commercial scale https://www.ose.com.tw/en/ic-services/memory-product-package/microsdsd

if you think that the precariously balanced tower of flash above is an inaccurate representation of what's going on, i can reassure you that
(a) this is exactly how it looks like, and
(b) SK Hynix is up to 24 layers already (not sure in what application)

When are people going to be buying old cards on eBay to scavenge the gold wire?

@RealGene @whitequark it's only got any value in bulk. No doubt some recyclers will offer bundles of 10,000 unsorted SD cards or whatever for the curious consumer to examine, but most of the waste will be consolidated then sent into a few large, experienced enterprises. I've friends who run an assay service with takes ground up chip waste samples direct from manufactuers, giving them a metals breakdown to assess how much to bid for barrels/iso containers which the sample was taken from.
