The developers who don't understand the relationship between relational algebra and SQL are the ones who end up confused why their query browned out prod.

It's not exactly the same thing, but the underlying lessons and mental model matter.

Of course, the move back towards nonrelational data stores these days may make the point moot.

Three decades of programming in various languages and at various companies and today's discussion is the first time (after all those years writing SQL used by those applications) that I've seen the term "relational algebra". My queries run great in production at various companies right now, including many I guarantee are widely recognizable.

Sounds like you're working hard to defend your ego rather than seeing the opportunity to learn and improve yourself.

You must be a delight to work with.
