We definitely have a unique ability to change our world but whether that's an effective "ruling of the world" and "smart" is really debatable. While that may sound be glib "judging them by their results" is really a ridiculous notion. The "results" would be purely framed in human terms "who can solve puzzles" who can "think like we do".

A cat doesn't need to think like us to live in their cat world, a worm doesn't need to solve a puzzle to live and thrive. Yet they both have thrived for a long time and existed in a way let them persist with their environment in an equilibrium.

It seems pretty reasonable to frame intelligence as thriving within your environment and persisting, and humans have only been around a short time and driven our planet to literal environmental collapse. I'd contend it's equally reasonable to describe humans as some of the least intelligent species.
