Abstract: The ethical examination of modern technologies, especially those that use artificial intelligence, can be based on an approach that focuses not on the technology itself, but on the subject as a human-agent who can be the developer and user of this technology. In this article, we consider the concept of an ethical subject as an agent with the fundamental ability to make ethically significant choices. The peculiarity of such choices is that they are significant not only for society, but also for the ethical subjects themselves, who are always not only a means, but also the goal of moral actions. That is why such ethical subjects can be only persons or groups of people, but not technology, even the most advanced – otherwise it would be the goal of ethical choices for itself and for people. Ethical expertise of a technology capable of acting independently of a person is possible, as we believe, through its «training» to recognize situations of applying those solutions to ethical dilemmas that are provided by a person, and valuation of the results of such recognition. A part of such «training» may be worth providing not only to developers, but also to users, remembering the fact that all these solutions should also be brought into compliance with local legislative norms.
