Godot bans AI-generated code contributions

Godot, one of the most prominent open source game engines, announced it will no longer accept AI-authored code contributions. The HN thread's top responses range from indifference ('oh shoot, anyway') to principled disagreement ('why base the decision on what tools the author uses and not on the quality of their past contributions?'). Someone links to a growing index of 'slopfree' software projects making similar choices.

This is part of a broader pattern of open source projects drawing hard lines around AI-generated contributions, motivated by concerns about code quality, license contamination, and maintainer burnout from reviewing AI slop. The debate in the thread isn't really about Godot specifically. It's about whether AI tool bans are a principled stance or just gatekeeping.

The counterpoint worth taking seriously: the 'judge by quality not by tools' argument has merit in theory, but maintainers don't have unlimited time to review contributions, and AI-generated code tends to look correct while hiding subtle bugs. The ban is really a heuristic for maintainer bandwidth, not a moral statement.
