So if I understand correctly, you're leaving LW because you think LW is too hostile to AGI research and nanotechnology? I don't mind your decision to leave, but I'm not sure why you think this. My own impression is that a lot of us either feel unqualified to have an opinion or don't think AGI is likely any time soon.

I think you're way off if you believe that MIRI or LW are slowing down AI progress. I don't think MIRI/LW have that much reach, and AGI is likely decades away in any case. In fact, I don't even know of any work that MIRI has even argued should be stopped, let alone work they successfully stopped.
