+#### Erlang vs C: A Tar and Feathering
+
+[citation erlang paper]
+
+Erlang has only one clear benefit over C, which is dynamic code upgrading.
+However, there are ways of making C behave in a similar fashion with minimal downtime.
+Shuffler [citation] is a system for continuous randomization of code.
+Using techniques discussed in the paper, one could dynamically replace sections of a binary.
+Another, slightly hack-ish workaround would be to receive the upgrade, serialize the current state, and finally run the new binary based on the serialized state.
+
+Other than dynamic code swapping and poor error detection, Erlang does not offer anything that is not offered by a traditional OS.
+Isolation, concurrency, and message passing can all be accomplished with unix-style system calls.
+Why is this language not considered redundant?
