I wish I could disagree with you. Of my four last jobs, two were semantic web/knowledge graph and two have been deep learning. I get more satisfaction from ML/deep learning work.

That said, from a knowledge representation perspective, I love the idea of knowledge graphs, and sometimes they do have real efficacy.

I totally agree. My thesis advisor was doing semantic search research, I was the one doing ML. I never understood the need to organize information when you can just throw ML at it. But the research might be a stepping stone in AI further down the line, when you need to build exhaustive knowledge instead of "intuitive" knowledge based on pattern matching. So who knows what it's good for.
