Yes, only humans have the kind of consciousness and sense of selves as a sum total of memories and sunken choices.
For example, several orders of computers aboard a Boeing 747 represent with great fidelity many parts of the airplane body — moving parts of the wings, undercarriage, rudder — not to mention outside temperature, wind speeds, levels of fuel, and so forth. And yet we do not expect even the most integrated computer among the 747’s computer family to be “conscious” of what goes on in the plane, except in a metaphorical sense.
What is different about us? Plenty, I would say. Beginning at the top of the scale of differences, the 747 lacks a self in the sense that you and I have one. I have proposed that selves are built from, but not limited to, myriad, integrated representations of the structure and operations of our bodies, and of the sum total of memories of what has happened to our own body in its history.
