Again that’s consciousness. You’re right that consciousness is more relevant here but that’s not what OP asked. Sentience is marked by feeling. The ability to feel sensations. A sentient creature doesn’t just detect pain, it suffers. Sentience falls within consciousness, which is more the concept of those feelings being unified with a sense of self. AI is not sentient nor conscious.
Awareness is the most basic tier: information gets registered and influences behavior. A plant bending toward light is aware in a minimal sense. It doesn’t require any inner feeling, just functional responsiveness. Most people mean something richer when they use the word, but at its core, awareness is about detection and reaction, not experience.
Sentience adds felt experience. A sentient being doesn’t just detect pain, it suffers. There is something it is like to be in that state. This is the threshold that matters most ethically, because sentience is what makes harm meaningful. It’s about having experiences, not necessarily reflecting on them or understanding them.
Consciousness goes further still. It typically means experiences are unified into a coherent subject, a sense of being a self who is having them. Some definitions include self-reflection: knowing that you know, noticing that you’re noticing. This is what philosophers call the “hard problem,” because no one has convincingly explained why subjective experience exists at all, even in beings we’re sure have it.
Panpsychism does not mean everything is conscious in the way that humans are conscious. I’m on team quantum information panpsychism as theorized by Federico Faggin, the inventor of the microprocessor. He postulates that consciousness is fundamental since we are the observer, observed, and agent, and our willful observation causes the collapse of the wave function. It means our consciousness exists as a holographic projection which is channeled through our brains like a radio.
Human consciousness is like a thread running through time. There is always something it feels like to be you, even when you are idle or staring at a wall. You have an interior that never fully goes dark. It has texture, mood, and continuity, woven through every moment of your life from the inside.
