[Terr_]

The way I see it, "blockchain" (NFTs, etc) are less technologies and more business-plans to make money--perhaps in a slightly more-literal sense than usual--from available tools.

It's kind of like ride-share services: They didn't invent cars or databases or dispatching systems or phone-apps, and while their investment might have spurred some new tools/libraries/algorithms they use, the broader usefulness of those inventions doesn't flow backward to mean they have a good/sustainable business.

There are even cases like "private blockchain" where the fad-marketing is getting used to mislabel what is actually just a regular old distributed database of yesteryear.

Can we really call the car an "invention"? After all, both the wheel and the steam engine already existed.

Those techniques were already invented and in-use long beforehand.
