>And yet, after years of tireless effort and billions of dollars invested, nobody has actually come up with a use for the blockchain—besides currency speculation and illegal transactions. I quoted the opening line of the article. I think the author clearly includes Bitcoin millionaires, and NFTs, as "currency speculation." Inventory and logistics tracking is, as you say, not widely used enough to count. It certainly doesn't seem like it's been seriously adopted outside of pilot programs, or financial transaction/speculation. Blockchain is older than Kubernetes. Tonnes of large corporations successfully use kubernetes in production; basically no-one uses blockchain outside of smaller programs. I have seen it used successfully in some cases (indigenous elections), but you have to admit it still seems like a nascent industry trying to get it's footing outside of the fields the author specified.
