FWIW, the core assertion here isn't even LLM-specific. DSL design leans heavily on the idea of an expert author who understands the underlying data model well already. That is no less true in the meatspace world than it is for an AI.

DSLs look great if they let you write the code you already know how to write faster. DSLs look like noise to everyone else, including Gemini and Claude.

I used to be a big DSL booster in my youth. No longer. Once you need to stop what you're doing and figure out your ninth or eleventh oddball syntax, you realize that (as per the article) Everything is Easier in Python.

yep, im still mad pg SOLD US A LIE (use a secret weapon ancient language in an unmaintainable way that no one wants in the workplace and become a gazillionaire). But gullible people are easily misled (see cults etc).

> DSLs look like noise

Exactly right. Now that we're in the era of LLMs and Coding Agents it's never been more clear that DSLs should be avoided; because LLMs cannot reason about them as well as popular languages, and that's just a fact. You don't need to dig any further, to think about pros and cons, imo.

The fewer languages there are in the world (as a general rule) the better off everyone is. We do need a low level language like C++ to exist and a high level one like TypeScript, but we don't _need_ multiple of each. The fact that there are already multiple of each is a challenge to be dealt with, and not a goal what we reached on purpose.
