I love Beebo because he's literally a disabled person. It may not be intentional but his robot-ness can be read as an allegory to disability, not just explaining his quirks character-wise, but also how he is treated by other characters.

His classmates have preconceived notions of what an Ultimate Robot should be. He should be cool, and full of fun gadgets, can do awesome computer stuff, basically be smart and most importantly, useful to humans. But much to his classmate's dismay, the reality is he's a bit dumb, doesn't understand social cues and concepts, says weird things because of it, is physically weak and has back pain somehow and needs frequent check-ups with a tech expert like Miu Iruma to be able to function properly day-to-day. These traits makes him a quite "weak", having to depend on others heavily for his own survival.

Robophobia revolves a lot around the idea that for a robot to be deemed valuable, it has to serve a use; that the value of a being isn't inherent but dependent on their role in society. Robots, like disabled people, are shrouded in a veil of otherness. Anyone who isn't working at its fullest potential to optimize output is considered less.

I think it's important that Kiibo is stubborn with his entitlement to be respected for being what he simply is. He's firm in his identity as a robot regardless of what others may think of him; "to become human" isn't a personal goal he works towards. Beebo recognizes that his value is inherent to his being, and could not be any less proud of it.

Kiibo's talent, by definition, is that he's the best at just simply being. He's literally the Ultimate Creature Creation, the Thing of all time, and he's here to do nothing more than simply be himself and play.
