In response to Koplin and Wilkinson, I argue, first, that the uncertain clinical prospects of human-pig chimera based transplantation makes the reason to spend resources for clarifying whether such practice might imply serious ethical breach due to enhanced cognitive capacities of the chimeras rather weak. T he benefits of further pursuing this avenue of research is so uncertain, so that taking even very unclear risks of serious ethical breach (thus in need of clarification for justification of the research) is not worth the price in terms of spent resources, and therefore only limited resources should be spent to clarify such risk before the project is abandoned due to unacceptable risks . Second, I argue that as there are some reason to pursue this avenue further (and thus investigate the risk in question), the analogy to the notion of halting all farming of larger animals for food does not hold…
