If this gets really good, maybe we can dream of having a fully de-obfuscated and open source life. All the layers of binary blobs in a PC can finally be decoded. All the drivers can be open. Why not do the OS as well!
Decompilers already exist and are really good. If an LLM can do the same as these existing compilers, you can bet the lawyers will consider it an equivalent process. The main problem is legal/political, not technical.
