Regarding the measurement problem in QM - clearly a charged and divisive subject - what is your take on this problem? [I hope this is appropriate for this forum.] I would like your vote on the solution to this problem. Decoherence, non-linear collapse due to gravity, multiple universes, conscious observer required, and here is one of my favorites from the Quantum Cosmologists, the wave function doesn't collapse, you jump into a superposition of eigenstates. Also, I have read recently that collapse could be relative. Given these and any ignored but reasonable contenders, what is your vote and why? I can see the cannon fire between the ivory towers, what is the mood on the streets?
