Currently, domain specific languages written in YAML. I see these everywhere, from configuring individual utilities to managing giant architectural stacks. People get in their heads that YAML is more easily written and read than code, and so instead of just writing the code to do something, users have to deal with a bunch of YAML.

The drawbacks of YAML have been well-documented[1]. And I think it's worse now in the LLM era. If I have a system that's controlled via scripts, an LLM is going to be good at modifying those scripts. Some random YAML DSL? The LLMs have seen far fewer examples, and so they're going to have a harder time writing and modifying things. There's also good tooling for linting and checking and testing scripts to ensure LLM output is correct. The tooling for YAML itself is more limited, even before getting into whatever application-specific esoteric things the dev threw in.
