If the physical world consists only of efficient causality, how can we create computational intelligence (that is, thinking computers or hard AI) that exhibits final causality from physical processes? At some point the various efforts similar to DeepMind are going to hit this wall. Getting over it is going to require that either we use biological material (neurons, glia, etc) to bridge the gap or reproduce their extra-dimensional quantum features in hardware.
