For me as a human being, I do not know any sense in which I could claim that the universe is here in the absence of observers. We are together, the universe and us. The moment you say that the universe exists without any observers, I cannot make any sense out of that. I cannot imagine a consistent theory of everything that ignores consciousness. A recording device cannot play the role of an observer, because who will read what is written on this recording device. In order for us to see that something happens, and say to one another that something happens, you need to have a universe, you need to have a recording device, and you need to have us . . . In the absence of observers, our universe is dead.
