“Let me allow myself at this point the luxury of expressing a strong personal opinion, which would certainly be contested vigorously by some of my colleagues. It seems to me that the many-worlds interpretation is nothing more than a verbal placebo, which gives the superficial impression of solving the problem at the cost of totally devaluing the concepts central to it, in particular, the concept of ‘reality’. When it is said that the ‘other worlds’ are ‘equally real’, it seems to me that the words have become uprooted from the context which defines their meaning and have been allowed to float freely in interstellar space, so to speak, quite literally meaningless. I believe that our descendants two hundred years from now will have difficulty understanding how a distinguished group of scientists of the late twentieth century, albeit still a minority, could ever for a moment have embraced a solution which is such manifest philosophical nonsense.”
