“Superpredator” is not a scientific term. It was used as an “overconsumer” in one publication, as far as I can find, but that meaning doesn’t fit the narrative of your copypasta.
And we definitely don’t maintain domestication of other predators through our predatory ability. On the contrary, domestication and cultivation of other species is what allows us to domesticate carnivores.

We are omnivorous vindictive social apes. Don’t take that description lightly.

We also have two real superpowers:

• We’re the only animal on the planet that can scale stable social groups into millions while being individually complex. Some glitch of ours broke cranial limitations of the group size that other primates adhere to.
• We are the only animal to have developed languages with complex grammars. While other animals can exhibit complex signaling systems, and possibly learn grammars we develop, we effortlessly develop and learn grammars that allow us to express novel thoughts without waiting for evolution. Hell, our children develop throwaway languages as a side-effect of playing with each other.

Everything else is a consequence.

PS: Blue-green algae would like a word about that “extinction event” claim. PPS: Leave hydrogen unattended for long enough, and it will start arguing on the internet.
