Can I just make clear my role here. 1) I've had general conversation with Jonathan about CEA and MIRI, in which several of these criticisms were raised. 2) I checked over the numbers for the GWWC impact assessment. 3) I've also said that criticism in public is often productive, and that public scrutiny of CEA on LW would be helpful for people choosing between it and MIRI. 4) I saw a draft of the post before it was published.

I want to make it very clear that: 1) I do not endorse this post. 2) I did not do detailed fact-checking for it. 3) I do not want this post to be seen as my view, either in a private capacity or with my CEA hat on. 4) That I'm deeply sorry if my actions have harmed the reputation of CEA. This was never my intention.
