I found this very helpful and motivating to read — it feels like this made clear and specific some things I had more hazily been thinking about. Thanks for writing it up.

I'm interested in this question as well.

I like this a lot, and have found similar-ish framings useful in my own life.

I think the robustness-fragility point is a very good one, and want to highlight it as I haven't seen it in discussions about hubs much.

Thanks for doing this research.
