It's a question of degree. Humans are uniquely adaptable, but only on small/medium scales.

We don't have the evolutionary intelligence to manage a planetary ecosystem without destroying it through overconsumption.

Intelligence is partly about scope. The smarter you are, the wider your predictive horizon.

Humans are semi-smart - good at small/medium problems, not smart enough to understand, build and maintain very complex multimodal systems with many moving parts.
