While there was no Pope Leo XIV, Pope Leo XIII, who reigned from 1878 to 1903, addressed social issues arising from industrialization, which can provide insights into a hypothetical vision for a papacy in the age of Artificial Intelligence (AI).

Here's a possible vision based on Catholic teachings:

Ethical and Responsible Development

• Human Dignity: Technological development, including AI, must respect the centrality of the human person, whose place can never be taken by an algorithm or a machine 1. The inherent dignity of each human being and the fraternity that binds us together as members of the one human family must undergird the development of new technologies and serve as indisputable criteria for evaluating them before they are employed 1.
• Ethical Framework: AI should be developed and used in an ethical and responsible way 1. It should be guided by an ethic inspired by a vision of the common good, freedom, responsibility, and fraternity, fostering the full development of people in relation to others and to the whole of creation 2.
• Discernment: Careful reflection is required at every level to ensure that the development of AI remains at the service of men and women, fostering interpersonal relations, a healthy spirit of fraternity, critical thinking, and a capacity for discernment, especially in young people 1.

AI and the Common Good

• Serving Humanity: Scientific and technological advances, including AI, should be directed toward serving the human person and the common good 3.
• Avoiding the Technocratic Paradigm: AI should not promote the "technocratic paradigm," which perceives all the world’s problems as solvable through technological means alone 4. Human dignity and the common good must never be violated for the sake of efficiency 4.
• True Progress: Technological developments that do not lead to an improvement in the quality of life of all humanity, but on the contrary, aggravate inequalities and conflicts, can never count as true progress 4. AI should be put at the service of a healthier, more human, more social, more integral progress 4.

Specific Concerns

• AI and Warfare: The development and deployment of AI in armaments should be subject to the highest levels of ethical scrutiny, governed by a concern for human dignity and the sanctity of life 5. There must be a clear stand against all applications of technology that inherently threaten human life and dignity 5.
• Protection of Human Genetic Patrimony: Special concern must be shown for the protection of the human genetic patrimony, by prohibiting practices contrary to human dignity, such as the patenting of human biological material and the cloning of human beings 1.
• Discrimination: Vigilance is needed to ensure that the discriminatory use of AI instruments does not take root at the expense of the most fragile and excluded 6. It is unacceptable that decisions about someone’s life and future be entrusted to an algorithm 6.

The Church's Role

• Evangelization: The Church's social doctrine is an essential part of the Christian message, pointing out the direct consequences of that message in the life of society and situating daily work and struggles for justice in the context of bearing witness to Christ the Saviour 7.
• Dialogue: Dialogue among all actors is required, especially in discussions around the Global Digital Compact, to foster the humane development of new technologies 6.
• Promoting Human Rights: In the encounter between different visions of the world, human rights represent an important point of convergence in the search for common ground 6. There is a need for renewed reflection on rights and duties in the digital era, as the scope and acceleration of transformations have raised unforeseen problems and situations that challenge our individual and collective ethos 6.

In summary, a Pope in the age of AI would likely emphasize the ethical development and use of AI to serve the common good, protect human dignity, and prevent harm, while also advocating for dialogue and reflection on the implications of these technologies for society.
