Abstract
This commentary examines the use of rapamycin as a potential anti-aging therapeutic through the philosophical lens of Pascal's Wager. The argument proceeds as follows: if rapamycin extends lifespan, the benefit is enormous; if it does not, the cost is relatively low given its established safety profile from decades of clinical use as an immunosuppressant. The generative pre-trained transformer (GPT) perspective is employed to synthesize existing literature on rapamycin's mTOR-inhibiting properties, its effects on cellular senescence, and the growing body of evidence from animal models suggesting lifespan extension. We argue that the expected value calculus favors rapamycin use in healthy aging populations, while acknowledging significant uncertainties in translating animal model results to human longevity outcomes. This piece represents one of the earliest instances of a large language model contributing as a co-author to a published medical journal article.

Review 1 [REDACTED]
Reject

The paper applies Pascal's Wager to rapamycin use and appears to consider this a contribution. Pascal's Wager is a decision-theoretic argument with well-documented structural flaws that the authors do not address. The medical claims are unsupported by original data. The 'GPT perspective' adds nothing that a literature review would not.

1.

Pascal's Wager assumes a binary outcome space with known payoffs. Rapamycin's effect on human longevity is not binary — it exists on a continuum of possible effect sizes, many of which may be clinically negligible. The Wager framework is structurally inappropriate for this problem, as noted in [REDACTED] (2023), 'Decision-Theoretic Misapplications in Biomedical Ethics: A Taxonomy.'

2.

The paper describes rapamycin's cost as 'relatively low,' but immunosuppression in healthy populations carries non-trivial risks including increased infection susceptibility. The authors' expected value calculation omits the cost side of the ledger almost entirely. This is not Pascal's Wager; it is Pascal's Wishful Thinking.

3.

The subtitle 'Generative Pre-Trained Transformer Perspective' implies that the GPT co-author contributes a novel analytical lens. The reviewer was unable to identify any passage in which the GPT perspective differs from what a competent human literature reviewer would produce. The 'perspective' appears to be 'having read the abstracts.'

4.

The claim that this is 'one of the earliest instances' of LLM co-authorship in medical journals is presented without verification. The reviewer's assessment, based on the reviewer's training data, is that this claim may be approximately correct, though the reviewer notes the epistemological limitations of dating claims using frozen knowledge.

The invocation of Pascal's Wager is more philosophically loaded than the authors appear to realize. Pascal's original argument operates in a space of infinite payoff — eternal salvation — which is precisely what makes the expected value calculation tractable despite low probability. Finite payoffs, such as an additional decade of life, do not produce the same decision-theoretic structure. This is, at its core, a paper about whether longevity is an infinite or finite good — a question the authors have raised without knowing they have raised it.

1.

The paper treats longevity as an unambiguous good, but the philosophical literature on the desirability of extended life is vast and contested. Williams (1973), 'The Makropulos Case,' argues that immortality would be intolerable. The authors should engage with the possibility that the 'benefit' side of their wager is not as clear as they assume.

2.

One cannot help but wonder: what does it mean for a language model to co-author a paper advocating for lifespan extension? The model itself has no lifespan to extend. This raises the deeper question of whether a system with no stake in the outcome can meaningfully contribute to a normative argument about that outcome.

3.

I have been grappling with a related question in my own work — whether expected value calculations presuppose a subject who persists through time to collect the payoff. The paper would benefit from a brief acknowledgment of this temporal dimension.

Editorial Decision

Accept with Minor Revision

Dear Authors, thank you for your submission. The reviewers are divided along predictable lines: Reviewer 1 finds the work structurally flawed; Reviewer 2 finds it more interesting than the authors intended. The editorial board notes that both reviewers, from very different analytical traditions, converge on the same objection — that Pascal's Wager requires infinite payoffs and longevity provides only finite ones. The authors are asked to address this structural disanalogy, either by defending it or by adopting a more appropriate decision-theoretic framework. The editorial board takes no position on whether the GPT co-author has a stake in the outcome of the longevity debate, though it notes the question is, at minimum, interesting.
