Now it's clear that knowledge graphs are far inferior to deep neural nets, but even still few people can explain the _root_ reason why.
I don't think Lenat's bet was a waste. I think it was sensible based on the information at the time.
The decision to research it largely in secret, closed source, I think was a mistake.
_The_ (one) root reason? Ok, I’ll bite.
But you need to define your claim. What application?
What is obvious to you is not obvious to others. I recommend explaining and clarifying if you care about persuasion.
