The free toolkit REA (Reverse Engineer Anything) allows AI agents to decompile and reverse engineer software, rapidly gaining traction with over 100,000 GitHub stars in a week. This has led to a surge in AI-decompiled game mods, console ports, and clones of paid software like Adobe products. While REA itself doesn't recover original source code, it facilitates the creation of functionally similar alternatives, raising concerns for software companies. Activision has already pulled AI-decompiled Call of Duty footage, and Bethesda issued a cease-and-desist for an AI-made browser game.
