The study aims to discuss the ethical and metaphilosophical foundations of posthumanism and their relation to human-machine studies. It analyzes Harrison's play “Marjorie Prime" (2014) as it constitutes a point of access for contemplations of boundaries, the nuance in exchange during social interactions, and the use of memory as a bridge for solace. Besides, it elucidates the potential panoptic features that seem to be overruling and bewildering human subjects annexed by new interactive technologies. The focus will be on studying the human-machine relationship and it raises thought-provoking questions about the potential benefits and drawbacks of advanced AI technology. It explores how the humanoid is seen as a potent tool that helps to reduce the cognitive impairment caused by dementia. On the other hand, it exposes the technological interventions that may trigger episodic memory change. It seeks to discover whether robots can transcend their liminal status and contribute towards the enhancement of the quality of elderly living conditions. Eventually, the current study proves that Harrison's play “Marjorie Prime" offers interesting and conflicting scenarios of future care that assist in detecting posthuman forms and modes of aging, relating, and being, and, most importantly, alert us to the ethical consequences of such scenarios.
