>The NoSQL movement is partially a reaction to antiquated database servers, and also a response to a fear of SQL borne from ignorance of how it works

I think the NoSQL movement was created for practical reasons. Since SQL didn't scale properly for certain applications, new kinds of databases had to be invented. What often happened is that a software used a typical SQL database with locks, and as that didn't scale, the locks were decreased to a point ACID wasn't theoretically guaranteed anymore. And it worked.

If the database in production doesn't guarantee consistency, you might aswell design a new database which is based on that idea, which is a core reason NoSQL databases were created. There's other reasons, too, of course..
