I am not sure if this question fits AI Stack Exchange so feel free to delete it in case it doesn't.
Recently I found out about somewhat famous Eliezer Yudkowsky and Machine Intelligence Research Institute he founded. Their philosophy and organisation seem interesting but I'm curious about their credibility. I'm pretty sure this is not a con and they seem to be producing a lot of articles. However, few of those are published and none in the journals mentioned here.
So, my question is: is MIRI doing a genuine high quality research?
