This is the weekly visible open thread. Post about anything you want, ask random questions, whatever. ACX has an unofficial subreddit , Discord , and bulletin board , and in-person meetups around the world . Most content is free, some is subscriber only; you can subscribe here . Also: 1: ACX Grantee Stephen Grugett (of Manifold Markets) wants me to announce his latest project: MNX , “a decentralized futures exchange targeting sophisticated traders and focused on the AI economy”. It’s a real-money platform where traders who want to hedge their AI plays can bet on benchmark progress, compute prices, etc. Announcement here , testnet here . 2: I think I got my tone wrong on last week’s Open Thread and made people think I was condemning the Harper’s article that mentioned me. I actually liked it and was just trying to clarify a few points. Please don’t get angry about it on my behalf. So as to not make things worse, I’ll banish further discussion of this to a comment .
