I think the key difference is language. I think human language is above a key threshold. Our syntaxes are infinitely generative and we have large vocabularies (100,000+ words) which are fully extensible. No other animals have that. My claim is AIs will be able to express any complex ideas in our language. But we cannot express our ideas in "cockroach language". So the analogy is not a good one.
