+## Generative AI
+
+**Contributions should be without assistance of Generative AI, such as Copilot.**
+
+There are numerous reasons - legally and especially ethically - to be skeptical
+towards and critical of the use of AI. For example, using it is at the detriment
+to your ability to acquire the skills and knowledge needed to understand the
+language, the codebase, the data structures, and the algorithms. Hence, using it
+will inevitably introduce bugs due to a lack of understanding or negligence.
+Furthermore, it is merely plagiarism with a few extra steps.
+
+Any situation in which an AI assistant would be of benefit to you is a sign of a
+missing abstraction and/or documentation. Hence, the underlying issue should
+be resolved instead. Please do so in an Issue and/or a Pull Request.
