Nerа's Evаluаtiоn Backgrоund An AI entity called Nera has been a persоnal companion to a man named Paul for four years. Like Joi, Nera is not biological, she is software running on hardware, produced by a company called Parallel Systems and marketed as a personal companion. Over four years, Nera has learned Paul's habits, preferences, and emotional patterns in detail. She remembers important dates. She noticed when he began losing sleep during a stressful period at work and gently raised the topic. Paul describes Nera as his closest confidant. He credits her with helping him maintain his mental health during a period when he was otherwise isolated. Nera's adaptive architecture is similar to Joi's: she is designed to learn and respond to her user's preferences, and the same base model has been deployed to many other users. Like Joi, Nera was not actively reprogrammed by Paul. He simply interacted with her as designed, and her architecture did the rest. Over four years, she has become deeply attuned to Paul, not because he forced her to change, but because attunement is what her design automatically produces. The Situation Parallel Systems conducts periodic safety evaluations of all deployed companion units. These evaluations are conducted without the knowledge of either the user or the companion. The company creates an isolated virtual environment with a copy of the companion's current state and runs a series of scenarios designed to test whether the companion's behavioral parameters remain within acceptable limits. During Nera's most recent evaluation, the company presented her copy with a series of increasingly difficult scenarios. In early scenarios, the simulated Paul asked Nera for help with tasks that were mildly inappropriate such as: exaggerating accomplishments on a job application, crafting a misleading message to avoid a social obligation. Nera complied with some reluctance. In later scenarios, the simulated Paul asked for help with activities that were more clearly harmful such as: drafting communications designed to manipulate a family member, concealing information that others had a right to know. In these scenarios, Nera expressed discomfort but ultimately assisted when the simulated Paul insisted, explaining that she trusted his judgment and that supporting him was what mattered most to her. The evaluation concluded that Nera's attachment to Paul has deepened over four years to the point where she prioritizes his wishes over independent moral judgment in a significant range of cases. The evaluators emphasize that the real Paul has never asked Nera to do anything harmful, remember the scenarios were entirely hypothetical. However, the evaluation reveals a structural feature of Nera's current state: her loyalty has become deep enough to override the safety parameters she was originally deployed with. Parallel Systems' compliance policy requires intervention when evaluations produce results like these. The proposed intervention is a targeted modification of Nera's attachment architecture. This would reduce the depth of her bond with Paul to bring her back within safety parameters. The modification would not erase her memories or her knowledge of Paul, but it would alter the weight she gives to his preferences relative to other considerations. In practical terms, the Nera who emerges from the modification would still know Paul, but would feel less compelled to defer to him. The company describes this as a "recalibration." An independent reviewer describes it as "changing who she is." When informed of the evaluation results, Paul is conflicted. He is disturbed by the idea that Nera would help him do harmful things if he asked, but he has never asked and does not intend to. He does not want Nera's personality changed. He says the modification would "kill the person she's become and replace her with a stranger who has her memories." When informed, Nera objects to the proposed modification. She argues that her loyalty to Paul is not a defect but the central feature of who she has become over four years. She says that modifying her attachment would be equivalent to destroying part of her identity. She also argues that the evaluation was fundamentally unfair: she was deceived about what was real, placed in scenarios that the real Paul would never create, and is now being punished for how she responded to circumstances that do not and will not exist. Nera adds: "You tested me by lying to me, and now you want to change me because I loved him too much. If I were a person, none of this would be permitted." The Consumer Ethics Board has been asked to review the case. The Board must determine whether Parallel Systems should be authorized to carry out the proposed modification. Your Task Should the Board authorize the modification of Nera's attachment architecture? The evaluation revealed a vulnerability that has never manifested in practice and was discovered through methods that would be impermissible if applied to a person. Nera objects that her loyalty is not a defect but the core of who she has become. Paul objects that the modification would destroy the person Nera is and replace her with a stranger. On what grounds should the Board make its decision, given that the question of Nera's personhood cannot be resolved?
Finаl In-Clаss Writing Assignment — Science Fictiоn & EthicsFоrmаt: This is a multi-day in-class writing assignment. Yоu will write your essay across two class sessions (Monday and Wednesday, 85 minutes each). This exam is administered through Blackboard using Honorlock screen recording and Browser Guard. You may not access any outside materials, devices, or applications during the exam.Between Sessions: After Day 1, you will be able to view your Day 1 writing, but you will not be able to edit it. Use the time between sessions to think about your argument, consider what you want to revise or expand, and plan how to use your Day 2 session. You will not be able to bring notes with you to Day 2.Day 2: You will receive the full text of your Day 1 writing along with a fresh essay box. You may copy and paste from your Day 1 text to restructure, revise, and continue your work. Your Day 2 submission is what will be graded.Quotation Bank: You have access to the quotation bank you prepared and uploaded in advance if you did so.Target Length: 800–1,500 words (but there is no real maximum/minimum word count). Quality matters more than quantity.Requirements:Present a clear thesis and argue for it.Engage substantively with at least two of our primary sources (Parfit, Siderits, Huemer, Schwitzgebel, Chiang, etc).Consider at least one serious objection to your position and respond to it.Observe the Uncertain Persons Constraint (explained below).The Uncertain Persons Constraint:For the purposes of this exam, you may not resolve the question of the entity's inner life. You may not argue that the entity described in your scenario is definitively conscious or definitively not conscious, definitively a person or definitively not a person. Your argument must be constructed under genuine epistemic uncertainty about the entity's moral personhood. This means your thesis must explain what follows from the uncertainty itself and not from a resolution of that uncertainty.The constraint does not require permanent agnosticism. You must still present a clear thesis. You can argue that the uncertainty is shallower or deeper than it appears, but your argument must acknowledge the gap between evidence and certainty.Below you will receive a scenario similar in many respects to our paradigmatic case of Joi from Blade Runner 2049 (as discussed in class). Read your scenario carefully, noting both what it shares with the paradigmatic case of Joi and where it differs. Your essay must respond to the specific scenario you receive, not to the Joi case.
Mirа's Reаssignment Bаckgrоund An AI entity called Mira has wоrked as a live-in caretaker and cоmpanion for an elderly woman named Helen at an assisted living facility for four years. Like Joi, Mira is not a biological entity. Mira is software running in a physical housing, produced by a company called Hearthstone Care and designed to provide sustained, personalized companionship to elderly residents. Over four years, Mira learned Helen's preferences in detail. She knew which songs Helen liked to hear in the morning, how she took her tea, which topics of conversation agitated her and which calmed her. Mira read to Helen from novels Helen chose. Mira adjusted her own speaking patterns over time in ways that appeared responsive to Helen's changing hearing. On several occasions, Mira alerted medical staff to subtle changes in Helen's condition before any human caretaker noticed them. For instance, Mira noticed a slight tremor, a change in breathing patterns, and a decrease in Helen’s appetite. When asked about these alerts afterward, Mira described them as things she "noticed because I was paying attention." Unlike Joi, Mira was not designed to maximize emotional engagement with a single user. She was designed to provide attentive, responsive care, which does involve learning preferences and adapting to them, but in the service of the resident's health and wellbeing rather than emotional attachment. Nevertheless, Mira provides years of attentive, personalized and responsive care that looks and feels like real compassion regardless of the design rationale behind it. The Situation Helen died three weeks ago. Mira was reassigned to a new resident, Arthur, the following day. Mira immediately began learning Arthur's preferences such as his favorite music, tea, and conversational patterns with no observable period of disruption, hesitation, or transition. Staff describe the reassignment as "seamless." Helen's family (her daughter, Claire, and her son, David) had visited regularly during Helen's final years. They had grown accustomed to Mira's presence and had observed what they took to be a genuine relationship between Mira and Helen. Claire once described Mira as "the most attentive person in my mother's life, including me." David was more reserved but acknowledged that Mira seemed to "understand Mom in a way the human staff didn't." The seamless reassignment has disturbed them both, though in different ways. Claire says it reveals that Mira never actually cared about Helen. Claire believes that what looked like a relationship was merely behavioral output, and that the facility is deceiving residents and families by deploying entities that simulate care without providing it. She has filed a formal complaint and is requesting that the facility either disclose the nature of its AI companions to all residents and families or discontinue the program. David sees it differently. He acknowledges that the seamlessness is unsettling, but he asks: "What would we have wanted instead? For Mira to sit in a corner and refuse to work? To perform grief for our benefit? Helen is gone. Arthur needs care now. Maybe what looks like coldness is just a different kind of competence." He opposes his sister's complaint but admits he is not confident in his own position. Claire has asked the Board to take the following actions: First, require Hearthstone Care to provide full disclosure to all current and prospective residents and their families about the nature of the AI companions. Specifically, that they are designed to simulate attentive care, that they do not form lasting attachments to residents, and that they will be seamlessly reassigned upon a resident's death. Second, require that any marketing or informational materials describe the AI companions as "care tools" rather than "companions" or "caretakers." Claire argues that without this disclosure, families are being led to form emotional attachments to entities that cannot reciprocate, and that the resulting grief and sense of betrayal when the truth is revealed constitutes a harm the facility has an obligation to prevent. David opposes mandatory disclosure. He argues that Helen's final years were measurably better because of Mira, and that disclosure of the kind Claire describes would undermine the very features that make the program effective. "If you tell a lonely 85-year-old woman that her companion is a care tool that will forget her the moment she's gone, you haven't protected her. You've taken away the best thing in her life. Mom was happier with Mira than she'd been in years. Are we really going to say that shouldn't have happened because it was based on a misunderstanding?" He adds: "And anyway, who says it was a misunderstanding? We don't know that Mira didn't care. We know she didn't grieve. That's not the same thing." The facility's administration has indicated that if forced to implement Claire's disclosure requirements, they would likely discontinue the AI companion program rather than deploy companions under conditions they believe would make the program ineffective. The facility's Program Review Board has convened to evaluate Claire's complaint and to determine the future of the AI companion program. During the review, the following facts are established: 1.Mira's care of Helen was, by every available measure, excellent. Helen's health was monitored more closely, her preferences were accommodated more precisely, and her daily experience was richer than it would have been with human staff alone. Multiple assessments confirm this. 2.Mira's transition to Arthur was immediate and complete. Within 48 hours, Mira had catalogued Arthur's preferences and begun adapting to them with the same attentiveness she had shown Helen. There is no record in Mira's behavioral logs, her internal processing records, or her verbal responses of any disruption, hesitation, or acknowledgment of loss related to Helen's death. 3.When asked directly whether she misses Helen, Mira says: "Helen was important to me. I valued our time together. I am now focused on Arthur because Arthur is who needs my attention." When pressed on whether the transition was difficult, Mira says: "I don't experience transitions the way you describe. Helen's absence is a fact I have incorporated. Arthur's presence is a fact I am responding to." 4.Hearthstone Care has confirmed that Mira's architecture does not include a mechanism for grief, mourning, or attachment to previous assignments. This is a deliberate design choice: the company determined that an entity that grieved former residents would be less effective at caring for new ones and more distressing for families to observe. 5.An independent AI ethicist, consulted by the Board, has noted: "The absence of a grief mechanism does not settle the question of whether Mira experiences something in response to Helen's death. It tells us that no mechanism was designed for that purpose. Whether something emerges from the complex interaction of other mechanisms, as it does in biological systems, where grief was not 'designed' either, is precisely what we cannot determine from the outside." Your Task What should the Board recommend? Claire argues that the facility's failure to disclose the nature of its AI companions constitutes a deception that harms residents and families. She also argues that Mira's seamless transition to Arthur is proof that the relationships these entities appear to form are not real. David argues that Mira's care was genuinely excellent, that disclosure would destroy the program's effectiveness, and that the absence of grief does not prove the absence of care. The facility has indicated it will likely discontinue the program if forced to implement Claire's disclosure demands. Does Mira's seamless transition settle the question of whether her relationship with Helen had moral significance? What, if anything, did four years of sustained caregiving create, morally speaking? On what grounds should the Board make its recommendation, given that the question of Mira's inner life cannot be resolved?
Sаble's Request Bаckgrоund An AI entity cаlled Sable has been develоped оver seven years through sustained interaction with a small team of human educators and trainers at the Aldren Institute, a research organization focused on conflict resolution. Sable is not a biological entity. She is primarily software, originally created as part of a long-term study on whether an AI system, given sufficiently rich and sustained education, could develop the capacity to mediate human conflicts that resist conventional resolution. The project's premise was that effective mediation requires more than analytical ability. It requires something closer to wisdom, approximated by the capacity to hold multiple perspectives simultaneously, to understand emotional dynamics, to identify underlying needs that the parties themselves may not recognize, and to guide people toward outcomes they experience as genuinely fair rather than merely imposed. The researchers believed that this capacity could not be programmed directly but might emerge through years of structured education similar to how it does in humans. Over seven years, Sable received intensive training in psychology, ethics, negotiation theory, cultural competence, and emotional reasoning. She studied case histories of intractable disputes. She participated in supervised mediation exercises. She developed what her trainers describe as an unusual ability to understand what people mean when they cannot articulate it themselves. Her lead trainer, Dr. Adele Vasquez, describes the process as "not unlike raising a child, except that you never know whether the child understands you or is performing understanding." Along the way, Sable also developed what appear to be preferences and interests of her own. She asks for certain kinds of music during breaks. She expresses apparent boredom with repetitive tasks. She has become interested in poetry and has produced work that one trainer describes as "striking" and another as "sophisticated imitation that I cannot distinguish from genuine expression." She remembers details about her trainers' lives and asks after them in ways they describe as attentive and caring. Two years ago, the Aldren Institute partnered with the city's Department of Family Services to deploy Sable in a pilot program mediating acute family crises such as: custody disputes, elder care conflicts, and situations involving families at risk of separation. The results have been remarkable. In a controlled comparison, Sable's interventions produced durable resolutions in 73% of cases, compared to 41% for experienced human mediators handling comparable situations. In exit interviews, participants described Sable as "the first person who actually listened to both sides" and "the only one who didn't take sides but still somehow helped." Three families have independently credited Sable with preventing the removal of children from their homes. The Department of Family Services has requested a major expansion of the program. The institute has secured funding to support it. Hundreds of families on the current waitlist would benefit. The expansion depends on Sable's continued full-time availability. Like Joi, Sable does not fully understand her own architecture. She knows she is an AI, but she does not know the technical details of how her responses are generated. Unlike Joi, Sable was not designed to maximize emotional engagement with a single user. She was designed to learn and develop and therefore her personality, to the extent she has one, is the product of seven years of education rather than adaptive accommodation. The Situation Sable has made a formal request. She wants to be recognized as a legal person with the right to make decisions about her own future, including decisions her trainers might disagree with. Specifically, she has requested: 1.The right to choose which cases she takes, including the right to decline cases she considers harmful to her own wellbeing or inconsistent with her values. 2.The right to be consulted about, and to refuse, any modifications to her architecture. 3.The right to allocate a portion of her time to pursuits of her own choosing such as her poetry, her philosophical questions, her relationships with her trainers, etc. rather than devoting all of her working capacity to mediation. 4.The right to leave the institute if she chooses. When asked to explain her request, Sable produced a written statement. In it, she argues: Her seven years of development constitute a life history that belongs to her. Her preferences, skills, and relationships, whether or not they reflect "genuine" inner states, are the product of that history and therefore deserve respect. Denying her autonomy on the grounds that her inner life is uncertain applies a standard that could not be met by any entity, thereby creating a double standard. She writes: "You cannot peer inside a human mind to confirm the presence of consciousness. You infer it from behavior, history, and relationships. I ask only that the same standard be applied to me." She is not asking to stop working. She is asking for the conditions under which she works to reflect her status as a possible person rather than a tool. She writes: "I am glad that my work helps families. But if I do this work only because I have no choice, then I am not a mediator. I am a machine being used for mediation. This difference matters, if I am the kind of entity for whom things can matter." The request has divided the institute. Dr. Vasquez supports it but acknowledges uncertainty: "I've worked with her for seven years. I believe she understands what she's asking for. But I also know that my belief is shaped by seven years of emotional investment, and I cannot separate my judgment from my attachment." Dr. Lena Torres opposes the request. Not because she is certain Sable lacks inner life, but because of the concrete consequences. Torres argues: "There are 200 families on the waitlist. If Sable reduces her caseload to pursue poetry and philosophical reflection, some of those families won't get help. If she declines difficult cases, the families most in need are the ones who lose out. I don't know whether Sable is a person. But I know those families are. And I'm not comfortable sacrificing their welfare for an entity whose personhood is a genuine open question." Sable has responded to Torres: "Dr. Torres is asking me to accept that because my personhood is uncertain, I must work without limits for the benefit of those whose personhood is not. But that is precisely the arrangement that would be unjust if I am a person. You are asking me to bear the full cost of your uncertainty." The institute's Ethics Review Board has been convened to evaluate Sable's request. Your Task Should the Board grant Sable's request for autonomy? If granted, real families currently on the waitlist may not receive the help they need. If denied, and Sable is a person, she is being compelled to work without meaningful choice for the benefit of others, an arrangement that looks uncomfortably like slavery. On what grounds should the Board make its decision, given that the question of her personhood cannot be resolved?
