Hacker News is famously built with Arc[^1] and I know that users don't care about your tech stack[^2]. BUT, I'm really interested to know, if you had to rebuild HN today, what tech stack would you choose? (the answer is very unlikely to be Arc, right?)

This is to consider all the existing features of HN (auth, comments, updates, text-heavy, etc) but also the "hidden" features like content moderation, filtering bots, shadowbaning, high availability, API, and etc.
