AI is mass decompiling games. That's both awesome and scary.

What happened
Simon Willison link-posts to indie game developer Popcar’s argument that AI-powered decompilation of existing games is now happening at scale, enabling mashups and a boom in preservation projects that get old games running on new hardware, often in browsers via WebAssembly. Popcar frames the upside as better software ownership after servers shut down, but warns the same capability applies to any software: paid games or apps can be decompiled, reused, stolen from, or open-sourced against the owner’s will.
Why it matters
If you ship a paid downloadable app or game, this is a concrete risk to plan around: the text claims AI decompilation makes reverse engineering cheaper and harder to stop, so closed binaries are less of a moat and an unwanted fork is more plausible. For preservation-minded builders, the same trend is an opening to port and keep old software alive via WebAssembly; for founders, decide how much defensibility should come from licensing, services, or community rather than distributed code alone.
Discussion angle
Where is the line between preservation/user ownership and unauthorized cloning? Use Popcar’s claim that any paid app can be open-sourced against your will to ask what part of your product would survive an AI-assisted decompilation wave, and what you would change now.
