This was never a consensus view among supporters of Bohr. The idea was floated by Wigner, but was eventually laughed out of court when it degenerated into silly arguments about whether the consciousness of a mouse could collapse the wave function, while the consciousness of an ant could not. The whole idea was seen to be absurd. So Deutsch's ridiculous attempt to demonstrate the falsifiability of many worlds collapses in gales of laughter.
