Is there a word in the rest-of-the-world that means "everything that supports the core work and allows other people to focus on the core work?"

I hadn't looked into the details of Windfall Clause proposed execution and assumed it was prescribing something closer to GiveDirectly than "CEO gets to direct it personally." CEO gets to direct it personally does seem obviously bad.

The "disadvantaged background" thing does turn out to show up in the top several google results, so, does seem like a real thing, although I also had no idea until this moment and would have naively used the term "talent search" in the way you describe.

Another angle on this (I think this is implied by the OP but didn't quite state outright?)

All the community-norm posts are an input into effective altruism. The gritty technical posts are an output. If you sit around having really good community norms, but you never push forward the frontier of human knowledge relevant to optimizing the world, I think you're not really succeeding at effective altruism. 

It is possible that frontier-of-human-knowledge posts should be paid for with money rather than karma, since karma just isn't well suited for rewarding it. But, yeah it seems like it distorts the onboarding experience of what people learn to do on the forum.

A related, important consideration when Lightcone arranged to buy the Rose Garden Inn (for similar reasons as Wytham Abbey), is that the Inn can also be resold if it turns out not to be as valuable. So thinking of this as "15 million spent" isn't really right here.

(it'd be handy to have a link in the opening paragraph so if I wanna avoid spoilers I can go do that easily)

I'm not sure what your imagining, in terms of overall infrastructural update here. But, here's a post that is in some sense a followup post to this:

Where are you expecting to find your audience? (I feel surprisingly ignorant on how journal projects like this bootstrap their way into wider readership)
