I think it’s more likely we can preserve our ego rather than our consciousness. For instance, create an AI replica of yourself that accurately behaves the same way you do. Although you would be dead, your ego can carry on living and responding to changes in the external world, and people could have interactions with you that accurately simulate how you would respond to them long after you’re gone. And as your ego learns about the world, it develops opinions closely similar to opinions you would have based on your life experience. Perhaps in this way people in power could remain in power indefinitely.
