Gorilla playing with his son

Human are primates, even. But what bothers me is having great apes in zoos. It's even worse with chimps. They're way too conscious to live in a glass cage. Or maybe they're fine with it, and I'm just projecting. They have less neocortex than we do, so abstract and hypothetical thinking is a priori harder for them, and they would have difficulties answering if we asked what they'd prefer. I'm so confused about all this.
