But Singer is acutely sensitive to the potential risks of any notion of lives not worth living.
I’m not sure what you mean by “sensitive”, it certainly doesn’t stop him from being at the cutting edge pushing in that direction.
Either way, the case for the expanding circle doesn’t depend on an alleged growth in empathy per se. If, as I think quite likely, we eventually enlarge our sphere of concern to the well-being of all sentience, this outcome may owe as much to the trait of high-AQ hyper-systematising as any widening or deepening compassion.
By way of example, consider the work of Bill Gates in cost-effective investments in global health (vaccinations etc) and indeed in: http://www.thegatesnotes.com/Features/Future-of-Food (“the future of meat is vegan”). Not even his greatest admirers would describe Gates as unusually empathetic. But he is unusually rational—and the growth in secular scientific rationalism looks set to continue.
You seem to be confusing expanding the circle of beings we care for and being more efficient in providing that caring.
Cruelty-free in vitro meat can potentially replace the flesh of all sentient beings currently used for food.
Yes, it’s more efficient; it also makes high-tech Jainism less of a pipedream.
