Such dinosaurs have not yet become extinct. No currency produces anything! Even gold is not backed by anything, it is used in jewelry precisely because of its elite status and high cost. And such volumes are not needed for technology at all. I think technology would benefit if it became cheaper. Any currency lives only on agreements and trust. This is not a distinctive feature of Bitcoin. Buffet is used to investing in manufacturing companies, this is good advice, but currency is a completely different area.
