Someday science might produce gene therapies or brain implants that eradicate schizophrenia and other mental illnesses. We will then face a momentous choice, because such technologies could also conceivably cure us of common unhappiness and angst. We might become so content, even blissful, that we cease agonizing over who we are. The mind-body problem will no longer be a problem, because we will no longer be human. In that world, perhaps, Freud will finally be dead.
