As soon as blockchain is even mentioned on HN, everyone loses their freaking minds. For some people that tout themselves as intellectuals, they just seem to parrot that 'blockchains are useless' without even taking a cursory look into the technology. It seems to me that a lot of people here fall into the category of ultracrepidarianism.

I'd argue that the usefulness of something is defined by what it can do, not the technologies used to implement it.

Or maybe after much research and some testing they conclude (correctly) that "blockchain is useless."

If that were true, then they would come to a different conclusion. There are several examples of useful applications that are live today that would be otherwise impossible without a public programmable blockchain.
