> Thank you NoSQL

Diversity and competition makes for better outcomes. I was never on the NoSQL bandwagon but even then I could see the benefits for its users. Namely schemaless documents for rapid development and relatively easy horizontal scaling. From those we got things like Firebase and a slew of NewSQL databases. Some SQL databases now have horizontal scaling in their roadmaps.

> It's hard to correct people's understanding when they learn things wrong the first time

Don't have a good solution to this. Trouble is that the 'first time' is learning and any amount of hand waving and thought experiments isn't enough to refute what they've learned combined with what they've yet to learn. No pain, no gain I suppose.
