Another in a recent series of really excellent podcasts (e.g., this and this are examples of thought-provoking recent ones), this is my favorite take so far on the ossification issue. Vijay is a legend, and as usual is thoughtful and articulate.
The real value for me, though, came from the other guy, Brandon Black, who I'd never heard of before. A key part of his take was: the most crucial components of btc's value is that it's verifiable and uncensorable, and for that to be true it has to be maximally decentralized, not just in the obvious way of people being able to run nodes, but wrt the second-order influences that would allow (or prevent) people from having sovereign control over their own funds. The features afforded by the base layer will powerfully contribute to that; and so we need to concern ourselves with the ends, not just the means.
Many such aspects of this issue were surfaced, all well-reasoned, thoughtful, subtle. Should be an aspirational model for btc discussion.
