I'm very interested in the nature of animal consciousness & communication, because I think it informs the fundamental nature of our own experience.
I think humanity is becoming more empathetic as a whole, because other living things are being recognized as sentient minds.

This video speaks for itself, and needs no philosophical debate. It shows chimpanzees from research laboratories, who were locked in cages for 30 years, being released into a sanctuary.
I can't see how a person with any empathy couldn't look at these chimps & recognize the experience they must be having when setting foot outside for the first time in decades.
