these VCs have scams like Ethereum which they claim to be p2p networks but all the people making money of this don't even know where the peers are on this p2p network.
The validation nodes run on handful of hosted nodes on a software(ethereum) that changes it's source code and make it backward incompatible all the time, making it centralized at both who develop that code AND the handful of nodes that run it.
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.
