In the time it took me to learn a new programming language, my kid learned how to be a whole entire human being. Including free thought and autocorrect mode. I don’t know what makes us special in the animal kingdom, but watching that happen certainly feels special. Do whales feel the same way about their young?
Whales almost certainly do not feel the same way. They feel like whales about their young. That's not to discount whales: that feeling may be profound and emotional for them. But it's probably alien to the human experience.
I’m sure their sensory experience is different from ours, but is the feeling truly alien? We share enough genetics to share the same brain chemicals, for one
For starters, whales aren't tool users. So it'd be something of a surprise if evolution had programmed them to feel joy when their offspring use tools. Humans, on the other hand, seem to get a bit of a kick out of teaching other people (especially kids) to do things which makes a lot of evolutionary sense given how strategically central tools are to our species.
I feel that people who study animal intelligence started with the dictum "don't assume similarity to humans" and immediately interpreted it as "assume dissimilarity to humans".
