You are saying 1) other people have said the same thing and 2) you don't like the particular way he said it. Those can both be true, but that isn't even close to "consistently wrong with all their predictions".

Some that turned out to be wrong include: singularity by 2021, singularity by 2025, 70% chance of human extinction between 2003-2015, and that his team would build "final stage AI" reaching transhumanity between 2005-2020 ("probably around 2008 or 2010"). His only correct prediction to date has been that AI would win gold in the IMO by 2025.
If you have examples of other predictions of his that have come true, I'd be interested to hear them.
I don't think there's much to be gained out of hashing out whether every prediction Yudkowsky has said was right or wrong: I likely directionally agree with you there, as I also find some of his more extreme predictions to be inaccurate. I mostly take issue with "consistently wrong". The results in longtermwiki are not "consistently wrong". He's definitely wrong sometimes. But consistently?
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.
