“As much as we might wish, they cannot replace human beings in our lives.”
I beg to differ. I would much, much rather be with my dog than about 6 billion other people, the vast majority of whom hate me because (1) I’m an American; (2) I am a male; (3) I am a Christian; (4) I am heterosexual; (5) I am a gun owner. My dog sees absolutely nothing wrong with any of the five.
But, finally, they just can't replace what we should have from human beings.
