Digital Human Storage hasn't made interrogation obsolescent, it's just brought back the basics. A digitised mind is only a snapshot. You don't capture individual thoughts any more than a satellite image captures an individual life. A psychosurgeon can pick out major traumas on an Ellis model, and make a few basic guesses about what needs to be done, but in the end she's still going to have to generate a virtual environment in which to counsel her patient, and go in there and do it. Interrogators, whose requirements are so much more specific, have an even worse time.
