The article examines the split in the open‑source community over AI‑generated contributions, contrasting strict bans by projects like Vim Classic and Redox with the majority of major projects that now accept labeled AI code, and explores the resulting policy experiments, legal concerns, and security implications.
The article examines the widespread practice of “rescuing” borderline‑failing students in Chinese universities, modeling teachers' decisions with an expected‑utility framework, exploring incentive structures, threshold effects, and collective‑action dilemmas that drive grade inflation and its long‑term consequences.
