Some people don't. I consider animals, at least the animals people mostly eat, to be conscious, sentient, and capable of suffering, so I don't eat them.

I do not, however, consider matrix multiplication plus randomness to be sentient or conscious, and I have absolutely no compunction about turning off the computers where I run AI models. And, I have no problem closing a Claude session that I will never come back to. I do that a dozen times a day.
