I'm in the no-AI camp, but for this case, I find it interesting, especially since there's little obfuscated C online, and LLMs cannot infer intention from the actual code. Did you spot any entries with LLM support?
Also, the reverse is interesting: how well can they guess the function of the obfuscated code?
Yeah, Claude, Grok and Gemini immediately recognized it as a SUBLEQ VM (and worked out from there all the details), only chatgpt got stumped and just said it was a "visual simulator".
All the big labs have plenty of proprietary (i. e. paying PhD holders good money for writing stuff) and synthetic training data now compensating for the lack of "naturally occuring" SUBLEQ and similar stuff.
