WBE singleton or faster-than-realtime research project conducted by WBEs seem to be the only feasible scenarios for gaining more time for solving FAI before a global catastrophe or significant value drift. On the other hand, WBE tech released into the wild would probably quickly generate a humane-value-indifferent AGI (either the old-fashioned way or via value drift of modified uploads or upload-based processes).

(A half-point between that and a FAI is running an AGI that implements a human-conducted FAI research project specified as an abstract computation.)
