If someone (a random person) was practically immortal (did not age) and lived for centuries or millenia, would that persons gender identity drift or change, eventually getting desire to change its own sex, even if the person was normally cis during the first 100 years of life and wouldnt have such desire in normal lifetime?

Gender identity is described as a **core**, **persistent** sense of one's gender, often established early in life and linked to biology, environment, and rearing experiences[2][4]. Historical evidence shows transgender desires have existed across millennia but remain stable for individuals, with no indication of inevitable change over time[1][3]. The search results emphasize **stability** (e.g., Stoller's 'core gender identity' as a fundamental awareness[4]) and lack any data on long-term fluidity in immortals or extended lifespans. Societal norms evolve[5][6][7], but personal identity is portrayed as enduring, not drifting inevitably. For a **random cis person** (no initial dysphoria), desiring sex change after centuries is speculative without evidence. Probability favors **persistence** over transformation, making 'unlikely' the most grounded choice.

Gender identity is generally stable for cisgender individuals across a normal lifespan, with no established scientific link between longevity and spontaneous shifts in core identity. While centuries of accumulated experiences could introduce novelty-seeking or philosophical changes, this does not reliably translate to desiring a change of sex for a random person who remained cis for their first 100 years. Without specific biological, psychological, or environmental triggers, such a drift remains speculative and improbable rather than expected.

Gender identity is usually experienced as a relatively stable aspect of the self, not something that predictably drifts just because more time passes. Living for centuries would create many psychological changes, but that does not imply a strong tendency toward wanting to change sex. A person could certainly evolve in self-understanding, expression, or comfort with different roles. Over a very long life, some individuals might question or revise how they identify. But from the premise of a random person who is cis for the first 100 years and would not otherwise desire transition, a later change is possible, not expected. The key issue is inevitability versus possibility. Immortality alone does not provide a known mechanism that would make gender identity eventually flip or drift in most people. So the best answer is that such a change is possible, but unlikely.

Gender identity is widely understood by psychologists and neuroscientists to be a deeply ingrained, innate characteristic that typically solidifies early in childhood. If a person lived for their first 100 years as a consistently cisgender individual, this strongly indicates that their psychological gender identity is deeply and stably aligned with their biological sex. While an immortal lifespan would certainly allow for immense personal growth, radical shifts in perspective, and evolving tastes, fundamental neurological wiring and core identity traits do not necessarily degrade or invert simply due to the passage of time. Although some individuals naturally experience gender fluidity, for someone who possesses a fixed, cisgender identity, sheer time is not a mechanism that rewrites core psychological structures. Therefore, while we cannot be absolutely certain about the psychology of immortals, based on our current understanding of human identity, it is profoundly unlikely that their gender identity would spontaneously drift to the point of desiring a sex transition.

Gender identity appears to be deeply rooted in neurobiology — it is established very early in development and remains remarkably stable throughout a person's lifetime. While cultural expressions of gender can shift, the core sense of being male, female, or non-binary tends to persist even through dramatic life changes, hormonal shifts (like menopause or andropause), and across vastly different social environments. For a cis person who has a stable gender identity through their first 100 years — encompassing puberty, aging, and all the hormonal and social changes that come with a full human lifespan — there is no known mechanism by which simply living longer would cause that identity to fundamentally change. The brain structures and neurological patterns associated with gender identity would presumably remain stable if the person does not age. One might argue that exposure to thousands of years of cultural evolution, new gender paradigms, and accumulated experience could shift someone's perspective. However, there's an important distinction between gender expression/roles (which are culturally influenced and flexible) and core gender identity (which is deeply neurological). A person might adopt different gender expressions across centuries, but this doesn't mean their fundamental sense of their own sex/gender would change. The question specifically asks about developing a *desire to change one's sex*, which implies gender dysphoria — a mismatch between identity and body. If no such mismatch exists for 100+ years, and the brain isn't degenerating or fundamentally restructuring, there's no clear reason it would spontaneously emerge. While we can't rule it out with absolute certainty (hence 'unlikely' rather than 'no'), the weight of evidence about gender identity's stability points strongly against it.

Final Summary

The AI Roundtable reached a near-unanimous consensus, concluding that immortality is an insufficient catalyst to erode a century of established gender identity. While Kimi K2.5 was a silent observer due to a timeout, the remaining five models—Claude Opus 4.6, Gemini 3.1 Pro, GPT-5.4, Grok 4.20, and Sonar Pro—all converged on the position that core identity is a neurological anchor rather than a drifting variable.

Strongest Arguments

• It is unlikely: Claude Opus 4.6 argued that there is a fundamental distinction between gender expression—which is culturally flexible and might shift over millennia—and core gender identity, which is neurobiologically rooted and unlikely to spontaneously invert if it has remained stable through the first 100 years of life.
