EY was influenced by E.T. Jaynes, who was really against neural networks, in favor of bayesian networks. He thought NNs were unprincipled and not mathematically elegant, and bayes nets were. I see the same opinions in some of EY's writings, like the one you link. And the general attitude that "non-elegant = bad" is basically MIRI's mission statement.
I don't agree with this at all. I wrote a thing here about how NNs can be elegant, and derived from first principles. But more generally, AI should use whatever works. If that happens to be "scruffy" methods, then so be it.
This seems like a bizarre statement if we care about knowable AI safety. Near as I can tell, you just called for the rapid creation of AGI that we can't prove non-genocidal.
I don't believe Houshalter was referring to proving Friendliness (or something along those lines); my impression is that he was talking about implementing an AI, in which case neural networks, while "scruffy", should be considered a legitimate approach. (Of course, the "scruffiness" of NN's could very well affect certain aspects of Friendliness research; my relatively uninformed impression is that it's very difficult to prove results about NN's.)
