But it demonstrates that LLMs struggle with basic reasoning.
A criticism of LLMs is that they're imitating without a understanding of what they're doing and without a clear plan, so this inability to solve a simple logic puzzle is very relevant.
If LLMs didn't struggle with reasoning problems then something like ARC-AGI wouldn't exist.
You can fool an AI as evidenced by them being fooled. They demonstrably appear to be working through a problem and get fooled by the wording of the problem. If you think differently, merely asserting it is not the way to convince people that what they see is wrong.
An LLM is (effectively) just a really, really elaborate "choose your own adventure" book.
It's not "working through" problems, it's just tracing a route through an pre-defined information space. It's not actually thinking, it just does a good impression of it.
If not, then perhaps this comparison is not the be all end all.
