Being you is (presumably) like something: it's nice being you, it's miserable being you, it's exhausting being you, it's invigorating being you... whatever it is like, I can't describe it but you experience it.
You have a subjective internal experience. A thermostat does not. An LLM presumably does not. A dog or a bat [0] presumably does.
