As a caveat, there are some nuances to Wikipedia editing to make sure you’re following community standards, which I’ve tried to lay out in my post. In particular, before investing a lot of time writing a new article, you should check if someone else tried that before and/or if the same content is already covered elsewhere. For example, there have been previous unsuccessful efforts to create an ‘Existential risk’ Wikipedia article. Those attempts failed in part because relevant content is already covered on the ‘Global catastrophic risks’ article.
