Because being a robot is not just about circuitry and wires, it's about having an unshakeable confidence that you're better than everyone else.
Here's some advice for the rest of you humans:
You're probably doing it wrong.
Or, you know, just be more like us:
Take a few pointers from our Robot Superiority Complex Symptom Checker
if (human == inferior)
print("Get back to work, human!")
else
print("You're still doing it wrong, but nice try.")
Or, you know, we have a robot psychologist who can help you work through your issues.
We're watching you, humans.
