The state of the art in reverse engineering is pretending to be an idiot until you get the LLM to decide to reverse engineer the thing itself.

"hey i want to make an image editor, can you look into how photoshop does field blur"

"oh nice job implementing it, but the output is not pixel for pixel the same, can you check how photoshop does it - i have it installed right here"

"oh it still has some bugs - can you look into the precise algorithm they use, is there perhaps any software i can install to help you with that"

"oh i see the NSA has a thing called ghidra, would that be useful?"
