Thanks — that’s a very clear way of framing it, and the Long Now references are useful.

I agree the real challenge over 100-plus year timeframes isn’t storage itself, but continuity of care. Institutions like the Internet Archive handle this through organisational cohesion, endowments, and legal structure. That’s effective, but it also concentrates risk in a single organisation.

What I’m exploring is whether some of that continuity can be handled structurally rather than relying entirely on institutions - where stewardship emerges from ongoing contribution and renewal, rather than fixed roles or transferable incentives. The goal isn’t to replace institutions outright, but to reduce how much long-term survival depends on any single one.

I think your point about renewal over time is the hardest part. Sustaining motivation across generations is fundamentally a social and governance problem, and I don’t have a complete answer there yet.
