Hacked Memory? Hacked Soul?

Is science fiction becoming fact? The Memory Hacker is working to make it so. Ted Berger wants to develop a hardware replacement for brain neurons, so that people suffering from alzheimer's disease, strokes or other maladies can have more satisfying and normal lives. He and others are working on what might be called a "bionic brain", whose parts can be replaced when needed.

Supposing that this science fiction becomes science fact, would this change your view about dualism and the mind-body connection? Do you think it would affect how people view the soul? If scientists do, one day, develop a way to "hack" memory as a computer hacker gains entry into a machine, could memory be replaced? Or soul?

What other questions that once were preposterous may one day be plausible?
