I update on things I read that I understand, or things from people I believe to be reputable.

So you are claiming that either you already understood AI/AGI completely when you arrived to LW, or you updated on LW/MIRI writings because they are 'reputable' - even though their positions are disavowed or even ridiculed by many machine learning experts.

EDIT: Oh, and you still haven't responded to the cat thing. Which, seriously, seems like a pretty big hole in the universal learner hypothesis.

I replied here, and as expected - it looks like you are factually mistaken in your assertion that disagreed with the ULH. Better yet, the outcome of your cat vs bird observation was correctly predicted by the ULH, so that's yet more evidence in its favor.
