Recovering from individual components crashing is a nice property, but in practice we don't use it at the kernel layer. But it does show up in other places -- when designing datacenters and web services (Netflix, Chaos Monkey, horizontally scaled web servers behind a pair of load balancers), and, in web browsers (Google Chrome is a bunch of processes; if Flash takes down one tab/process, the others keep running).
