The big difference is that NoSQL (and XMl, and...) were always primarily developer tools and the hype/investment was always scoped more-or-less to that environment. My parents never asked me about NoSQL, and celebrities didn't sell/promote IPOs for companies built around XML processing libraries... The author hits on this in the end: > There are some very real things to worry about in association with Blockchain. Cryptocurrencies are not investment strategies, and are not going to have any of the promised power-distribution and -equalization effects they peddle while their value and cost fluctuate so wildly. Companies and VCs investing in NoSQL databases really were trying to creating business around developer tooling. But most blockchain companies aren't selling themselves as developer tooling companies. The rest of the comparison seems less important than that distinction.
