One of the ultimate problems of moral philosophy is to determine who or what is worth moral consideration or not. "Morality" is a relative concept, which changes significantly with the environment and time. This means that morality is incredibly inclusive. The emergence of AI technology has a significant impact on the understanding and distribution of "subject," which has produced a new situation in moral issues. When considering the morality of AI, moral problems must also involve moral agents and moral patients. A more inclusive moral definition is necessary for extending the scope of moral consideration to other traditionally marginalized entities. The evolving ethics redefines the center of moral consideration, effectively reduces the differences, becomes more inclusive, and includes more potential participants. But we may still need to jump out of this binary framework and solve the problem by rewriting rules. It is a huge, complex systematic project to realize moral AI in education. To be a "trustworthy" and "responsible" companion of teachers and students, educational AI must have extensive consistency with teachers and students in terms of the moral theoretical basis and expected value. The deep integration of AI and education is likely to become the development trend of education in the future.
