The actual formal theorem is new and great, but the general battle of asserting the wave function's existence vs. non-existence (whatever either are supposed to mean) vs. saying "I don't know tell me more about the wavefunction and its experimental predictions working/failing" has been around for quite some time. Here's a nice write-up of the ridiculousness of someone definitively saying "I don't know why this works and therefore it doesn't exist!" http://lesswrong.com/lw/q5/quantum_nonrealism/ http://lesswrong.com/lw/q5/quantum_nonrealism/
