This was still the main AI textbook in 2014 when I did my MSc in the subject. It is what is rightly called a "seminal text" and there is not a single trace of Singularitarianism in it. It's not just "Norvig's book". Its authors are Peter Norvig and Stuart Russel. Is Stuart Russel ignored because he is not at Google?
The article really needs to cool down on the hindsight triumphalism. A lot of people were very optimistic about AI in the '80s (as earlier) because significant and continued progress had been made. Scientific progress, the continuation of the work of the Logicians in the '20s and Church and Turing's work in the '30s. Sure, people in the industry just wanted to make a quick buck, as they always do. But interesting science was being done and it is a big loss that the AI winter disrupted its course. Not because it could have led to autonomous vehicles and conversational agents. What we lost in the winter was the opportunity to discover new knowledge. That is a tragedy.
So I really don't understand where all the schadenfreude comes from, in the article. A big commercial project failed and took with it a whole branch of computer science. Who, exactly, benefited from this?
