As an experiment, I just now took a random section of a few hundreds bytes (as a hexdump) from the /bin/ls executable and pasted them into ChatGPT.

I don't know if it's correct, but it speculated that it's part of a command line processor: https://chatgpt.com/share/69d19e4f-ff2c-83e8-bc55-3f7f5207c3...

Now imagine how much more it could have derived if I had given it the full executable, with all the strings, pointers to those strings and whatnot.

I've done some minor reverse engineering of old test equipment binaries in the past and LLMs are incredible at figuring out what the code is doing, way better than the regular way of Ghidra to decompile code.
