I broadly agree with what he's saying, with a couple of caveats. His insistence that his view *contrasts* with the block universe is rather puzzling, as is his idea that there is some form of "becoming" in nature that in some way isn't embedded in space-time (or a multiverse equivalent) - this appears to be postulating an extra time dimension in which things change outside the normal one? Also, his comments about atomic nuclei being in stationary states and therefore not experiencing time (if that's what he's saying, I may have misunderstood) seems at odds with the existence of radioactivity.
