  2. Quoting Tim Schilling Quoting Tim Schilling — simonwillison.net · 21h ago · 💡 Opinion / Essays

    Tim Schilling critiques the detrimental impact of using Large Language Models (LLMs) in open-source contributions, specifically within the Django community, when contributors lack genuine human understanding. He argues that if a contributor doesn’t comprehend the ticket, solution, or PR feedback, their LLM use harms the project. Schilling emphasizes that open-source is a communal endeavor, and interacting with an LLM-generated “facade of a human” is demoralizing for reviewers. Over-reliance on LLMs without human comprehension undermines the collaborative and human-centric nature essential for open-source development. 💡 Why read it: It offers a critical perspective on the ethical and practical challenges of integrating LLMs into open-source collaboration, highlighting the importance of human understanding and community. 🏷 LLM, Django, open source, developer skills
