What if the self could persist after the body fails? That question sits at the center of a subscriber-only roundtable from MIT Technology Review on November 17, 2026, titled “Inside the Quest for Cognitive Immortality.” The session, led by science editor Mary Beth Griggs and senior editor for biomedicine Antonio Regalado, will explore emerging ideas for keeping the mind going beyond death—an ambition the publication describes as the pursuit of cognitive immortality.
Two Paths Under Discussion

The roundtable will focus on two speculative approaches. One is gradual brain replacement, a concept in which the biological brain is methodically substituted over time. The other is uploading memories to the cloud, which would aim to preserve personal recollections in digital form. Both ideas are presented as possible routes toward continuity of the self, though the event description frames them as areas of inquiry rather than established science.
These approaches differ in mechanism but share a common goal: sustaining the mind when the physical brain can no longer function. Gradual replacement implies a piece-by-piece transition, while cloud uploading suggests a more abrupt transfer of memory data. Neither method is presented as proven or imminent; instead, they represent the kind of far-thinking experimentation that the roundtable intends to examine.
Who Is Leading the Conversation

Regalado, who covers biomedicine, and Griggs, the science editor, will guide the discussion. Their combined expertise spans the life sciences and the broader implications of emerging technology. The event is scheduled for 17:00 GMT, which corresponds to 12pm EST and 9am PST. Access is limited to MIT Technology Review subscribers.
The roundtable is part of the publication’s biotechnology and health coverage, a section that regularly addresses long-range questions about the body, the mind, and the limits of medicine. While the session is forward-looking, it is grounded in reporting on real research and startup activity, including earlier stories about brainless human clones, technologies that simulate conversations with deceased relatives, and one researcher’s proposal to replace the brain little by little.
Why the Topic Resonates Now
Interest in cognitive immortality reflects a broader cultural and scientific curiosity about what constitutes a person. If memories can be copied or a brain can be swapped out neuron by neuron, the boundary between life and death becomes less clear. The roundtable does not promise answers, but it offers a structured conversation about the technical and philosophical questions that such possibilities raise.
For subscribers, the event provides direct access to two editors who track these developments closely. It also signals that the quest for cognitive immortality is moving from fringe speculation into more serious discussion among technologists and biomedical researchers. Whether gradual replacement or cloud uploading ever becomes feasible, the conversation itself marks a shift in how the idea of preserving the mind is being considered.
What to Expect
Attendees can anticipate a focused exploration of the two proposed paths, along with context from the editors’ reporting. The roundtable is not a product announcement or a clinical update; it is a subscriber-only discussion designed to unpack a complex and provocative subject. Those interested in the future of the mind—and in the ethical and practical questions that come with it—will find the session directly relevant.
The event takes place on November 17, 2026, and registration is available now for subscribers. For anyone following the intersection of biotechnology and health, it offers a chance to hear how two experienced editors frame the possibilities and limits of cognitive immortality.
