Mate its been a couple of days, I would think you'd be mad to expect perfection from an LLM reverse engineering job straight away.

As a proof of concept however it shows that we are at the stage where any malicious actor has a very low barrier to entry to cause large scale corporate espionage etc.

Do you mean that bad actors can reverse engineer photoshop and hack its users or that bad actors can whip out plausible photoshop clone with vulnerabilities and backdoors and hack users with that?

Past performance is not indicative of future results.

It's easy to create a set that looks as if it was a real city. It's infinitely more hard to create that real city.

But you're absolutely right that a set is all it needs for all sorts of (cyber) attacks.
