Thank you for sharing your thoughts. You’ve highlighted some great examples of DSLs that have become essential tools in software development, like SQL and Markdown. However, the success of these DSLs often lies in their universality, broad adoption, and well-thought-out design. These qualities make them more than just isolated islands—they are foundational tools backed by strong community support and decades of refinement.

The point of the original argument is not to dismiss DSLs entirely but to caution against the hasty creation of niche, poorly designed DSLs that solve narrow problems at the cost of maintainability, steep learning curves, and a lack of long-term viability. The challenge is that many developers underestimate the complexity of language design and overestimate the benefits of introducing a new DSL for a specific use case.

In conclusion, the advice is not to avoid DSLs altogether but to approach them with caution, ensuring they address real needs without creating undue burden on the team. Thoughtful design and a strong host language can certainly help, but they don’t eliminate the broader risks associated with creating domain-specific abstractions.
