I am a longtermist who thinks we’re at the hinge of history. I work at the Alignment Research Center. I’m involved in the effective altruism and rationality communities.

Find me on Alignment Forum, Discord(Mark Xu#7373), EA Forums, Email, Facebook, Github, Instagram, LessWrong, LinkedIn, Metaculus, and Twitter.
I generally cross-post high-effort posts to the Alignment Forum, LessWrong, or the EA Forums, so visiting my profiles on those sites is a good way to find my best content.
