If all living organisms gained sentience and intelligence on par with humans, which would be the apex predator?

Humans had quite the head start so I feel like we’d have a decent shot of winning out in most areas with superior weapons and stuff. Like it would be a while until a chimp with human intelligence could develop guns and nuclear technology.

If you’re in areas where we didn’t already eradicate the majority of animals that can fuck up a human that’s where you’d have to be scared. Like Africa still has lions and elephants and shit to be scared of.

Although one risk could be if a human becomes a traitor and starts arming the animals.
