Generally good, but this seems weak to me: "quantum field theory and general relativity are victims of their own success. For we need to go beyond them, since they face various technical and conceptual problems: such as the hierarchy and cosmological constant problems."
I cannot emphasize this strongly enough: we observe directly phenomena in the microworld that are irreconcilable with the most primitive assumptions of GR. It's not the overwhelming empirical success of QM that obliges us to accept a non-classical logic. It's direct observation.
