Spoken like someone who has never done reverse engineering of binaries.

Here are some examples of people using Ghidra. https://github.com/evyatar9/GptHidra https://github.com/likvidera/GhidraChatGPT https://github.com/tenable/ghidra_tools/tree/main/g3po

I suspect there are better ones being worked on though.

I think "[automated] disassembly" has a different implication than reverse-engineering; the latter usually involves more depth in the analysis of the binary, usually including more semantic-level considerations (i.e. this block is meant to do this, or this function is used from these different callsites). The best examples of this type of analysis seem to exist in the security community when going into the detail of zero-days, exploits, etc. I think LLMs either already can or will soon enter that space.
