The author is arguing that technology has challenged our perceptions of ethics and has begun to dictate our actions and beliefs in such a way that the moral separation between human and non-human objects is no longer a helpful function of Enlightenment thinking.
Technology, no doubt, has made ethical questions more prudent in our modern life. The author asks us to consider how an ultrasound ethically impacts humanity. We can see a baby long before it is separated from the mother, assess its value and identity. Before, a baby could not be detected to have a disease, but now that this is a possibility, the ethical question is on the table in abortion debates. Thus, technology, objects, have impacted human ethics in such a way that humanism as it stands may have limitations that need to be addressed heading into the future.
The author addresses Sloterdijk's _Rules for the Human Zoo_, a highly controversial take on humanism. In the 1999s, Sloterdijk was able to witness the burgeoning sector of technology and make a policy on ethics for the future. Sloterdijk and the author argue that morals should be expanded beyond just humanity and applied to nonhuman things, including animals and objects. The reason for this is that humanism and morals are ultimately rooted in linguistic conventions and can thus be expanded. This way, the moral dilemma surrounding technologies, some of which are inconceivable, can be addressed in the future.
The author raises some interesting questions, and I appreciated the moral dilemma presented. Ultimately, I feel as though the ethical framework surrounding objects is problematic because the moral framework would be coming from a human, either way. It is already a debate if morals are inherent or constructed (spoiler, I don't think morals can be logically defended as innate, given the existence of different cultures' perceptions of morality. Morality cannot be objective unless we ground those morals in a higher power above humanity in some way.) Therefore, this idea is limited in its assumption that humanism brings good, _objective_, ethical ideas to the table.
