Last year, an interview on the potential of AI to propagate an individual’s consciousness in the cloud after death grabbed my attention. It was about keeping enough information on a dead person, manipulating it using AI, and possibly downloading it into a humanoid robot, to simulate a living being. Is “digital immortality” possible? Here is the link to the interview with Alexandr Wang on the Shawn Ryan show: “Neuralink & Brain Interfaces.” Wang, the founder and CEO of Scale AI, is one of the youngest self-made billionaires in the tech industry. He believes that humans will soon be able to reproduce the personalities of the dead, given that sufficient data is available.
Digital immortality refers to using AI, neurotechnology, and large‑scale personal data to preserve or simulate a person’s identity after biological death. Saving a person’s memories, personality characteristics, communication style, and decision patterns allows for the reproduction of the individual as a simple chatbot or, with time, as a more advanced humanoid robot. Current research classifies this as a form of “informational survival” as opposed to biological survival. While current data-driven simulations are based on a person’s digital footprint in the form of messages, e-mails and recordings, future neural emulation could digitally reproduce brain structure and cognitive processes through brain computer interfaces and neural mapping. Jadhav et. al. (2025) have discussed this in their article “Digital Immortality: Preserving Consciousness through Artificial Intelligence”. According to the source, the terms “digital transcendence” and “digital consciousness” are also used to refer to this technical possibility, which is moving from the realm of science fiction closer to a tangible reality. They explain that although full brain simulation is still decades away, “partial forms like AI-based avatars are already examples that show digital continuity”, adding that this is “a new method to embrace the inevitability of death while maximizing the output of human intellectual and emotional legacy beyond biological bounds”.
As Syarova et.al. (2025) explain, technology is now capable of producing “authentic digital doubles” that not only preserve memories but also allow for interactivity in various forms:
• Text chat
• Voice interactions
• Virtual reality, where 3-d avatars interact with users
• Interactive learning from historical figures, as an educational application
• Emotional therapy to alleviate grief after someone’s death
(“Digital Immortality — A Comprehensive Survey of Technologies, Ethics and Societal Impacts”)
On the other hand, studying technical feasibility alone is not enough. These authors advocate a multidisciplinary approach including ethical implications, legal considerations, and wider social impacts.
Will dead teachers teach in the future one wonders? Who knows? Modern AI can already simulate the language patterns, conversational style, and emotional tone of individuals, besides replicating their decision making tendencies. Educational institutions might want to preserve – and even enhance - some of their most effective educators in this way. Education administrators should perhaps start considering this possibility, also referred to as "consciousness emulation", "virtual personhood" and "digital legacy".
Currently, no significant academic literature exists that focuses specifically on reviving dead teachers, using AI to preserve or continue a teacher’s pedagogy, or posthumous teaching agents modeled on real educators. This is an unfilled research niche.

As the author of the last article notes, digital communication can foster the illusion of presence, erasing the binary of gone or alive.
