ETS is isomorphic with a data table process that processes get and set (and etc) messages, but happens to be quite a bit faster.

If ETS is shared mutable state, so is a process with state that accepts changes, as chrisseaton posits. Of course, shared mutable state with clear boundaries between mutations is a lot better than shared memory where everyone can write and read things in bits and pieces.
