Some software is very resilient to changes; for instance, the Airbus A320’s primary fly-by-wire computers still use Motorola 68000 CPUs. Re-certifying new silicon costs millions for safety-critical systems. Regarding AI, many of the "hacks" documented in HAKMEM (AI Memo 239) have become fundamental techniques in areas such as bit manipulation, mathematical functions and algorithms, and algorithmic design. Now, back to the present time: making AI-generated code more accurate in any language is interesting research at MIT Press. https://news.mit.edu/2025/making-ai-generated-code-more-accurate-0418
