Yudkowsky said AI would be a problem when very few people taken seriously in the mainstream were saying it was going to be a problem. Saying "specific predictions are wrong" is missing the forest for the trees here.
People pushed back against his AI doom claims not because the idea that AI could be bad was unthinkable (just look at literally every SF story from the last 50 years featuring AI?), but because he specifically was worried about AI becoming God. That is no closer to happening than it was 30 years ago.
