This "communicativity" is a feature only enabled by fixing a certain execution model (roughly "everything is addressable bytes in memory"). Thus any languages that would support "communicativity" would necessarily need to adopt this model explicitly - which would deprive them of some abstractness, and, I think, even probably make them C-like. In other words, there is simply nothing other to do than "creating new worlds" (or creating a C).
