How much data has the world created in the last five years compared to the last thirty?
More than he guessed: IDC measured ~6.5 zettabytes created in 2012, ~64 in 2020, heading past 180 by 2025 — more data in the next five years than twice everything stored since digital storage began. It became the centerpiece chart of the next essay.

Is it 34 or 35 municipalities in Miami-Dade County?
34 — nineteen cities, six towns, nine villages, per miamidade.gov. The brain caught its own expert rounding up in speech and corrected the essay before it published.

Is the "4th R = Recovery" framing really yours?
No — a web search had attributed it to him and he does not claim it. Dropped from his frameworks. The brain now treats every web-sourced claim as provisional until the expert confirms it.

What actually comes after zettabytes?
Yottabytes, not petabytes (peta is six rungs smaller). And in 2022 the SI system added two more prefixes above yotta for the data age: ronna and quetta. The ladder now ends at quettabytes, a billion billion terabytes.

What should the sector learn from Cheyenne suspending data-center discharges after a Meta contractor contaminated the reuse system?
Four lessons in one incident: routine sampling closed the detection loop in weeks (the feedback worked); the regulation for fill-and-flush biology did not exist until after (regulation trailing the issue, again); one discharge took two plants offline for months (resilience is the minimum of your inputs); and a hundred other data-center cities have not heard the lesson yet — which is exactly the gap a shared case clearinghouse closes.
