It’s not a waste of time. As the boundaries of AI are pushed we increasingly struggle to define what intelligence actually is. It becomes more useful to test what models cannot do instead of what they can. Random tasks like the pelican test can show how general the intelligence really is, putting aside the obvious flaw that the labs can optimise for such a simple public benchmark.
The whole point of this benchmark is that it asks the model to work in a modality it is not trained in and does not understand well. The result is largely meaningless. This is just like the people who are endlessly surprised by the fact that a raw LLM does not work with numbers well, or miscounts letters. In short, this test benchmarks the intelligence of the person running it, not of the model.
