Why Linus Won't Put a National Anti-Fraud Center in the Linux Kernel

The article explains why integrating a national anti-fraud center into the Linux kernel violates core OS principles: kernels must remain neutral, minimal, and secure; adding application-specific logic with kernel-level privileges breaks least privilege, introduces instability, and undermines the open-source consensus that keeps Linux universal.

Stop Chasing AI-for-Kernel Papers: The Real Opportunity Is Kernel-for-AI

A veteran kernel engineer argues that while AI academia floods the field with "AI-for-kernel" papers, few reach mainline due to community conservatism and engineering gaps; instead, kernel developers should focus on "kernel-for-AI" optimizations—scheduling, memory, I/O for AI workloads—where real impact lies.
