I found this fascinating! Unitarity does seem to suggest that the future somehow equals the past, which does seem to leave a bit of explaining to do (why would time exist/happen at all?) I also like the way that the new 'isometry' method resolves this by extending into a new dimension. It reminds me of the idea of the self-organisation of space (from previously dimensionless information) proposed by process-physics back in the 90s.
