In a way I think you understood an important message I was trying to convey with this post. Taking the example of the dog you just mentioned, we might be the stupidest and weakest animals on the planet to its eyes. Humans need clothes to cover, houses as shelter, cars to move around, cooked food to eat... The prospective changes with the eyes of the observer, but it is undeniable that speaking a language is an enormous advantage when talking about learning. As a software engineer, today I know how to write a program not because I invented the processor, the hard drive, the DC, the binary language, the programming language(s) and so on, but because I learned from the knowledge humans acquired before me. This is something animals can't do and this limits their knowledge to what they can can learn by themselves in their own lifetime. But of course, as this is improvement for us it may be madness for the animal observer.
