Review for NeurIPS paper: Emergent Complexity and Zero-shot Transfer via Unsupervised Environment Design

Additional Feedback: Could you add a specific example/ problem that would be easily solved by defining it as a UED? I think it would help the paper in general. The agent for the Lava environment, that replaces walls with dangerous lava, is trained from generated maps with lava instead of walls? Additionally, the paper needs further proof reading, some minor mistakes I found: *Line 511: I wouldn't start a proof section saying "it would be nice to know that..." that is too informal *Line 512: "their" should be "its" *Line 40: Section?, i.e., referenced section is missing the number *Line 138: the function T M shouldn't be defined on S M? *Line 171: This sentence needs further explanation *Line 207: based on twice *Line 209: Figure? The Broader Impact section, specially the first paragraph is too speculative, automating jobs or automated weapons are general problems of the AI field, it should focus more on the impact of this specific work.
