So your definition of intelligence would be exactly equal to a human or some subset of them you choose? Could a dog solve ARC-AGI? Probably not. I would not say they lack intelligence. Same with a fruit fly. What if the calculator is powered by actual living neurons? I think you need to know where you actually think the difference between organic machine and intelligence is before making blanket statements.
A modern LLM in a loop with a harness for memory and behavior modification in a body would probably fool me.
"a harness for a memory" so it still requires external tools to work well. The whole point of this benchmark is to validate the systems can solve problems without any sort of outside help.
