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.
