tl;dr: Hobby programming communities (OSDev, LangDev, chess engines, demoscene, etc.) tend to reject LLM usage because the point of these pursuits is mastering difficult domains—the process is the product, not the working artifact.

The author argues LLMs work best as a force multiplier for existing experts, but in learning-focused niches they simply "rob us of the craft."
