Cyber Humanism is proposed as an evolution of Digital Humanism, repositioning the humanities as active agents in shaping knowledge, meaning, and agency in algorithmic societies. Rather than positioning humanists as external critics, it frames them as epistemic co-designers, actively embedding reflexivity, cultural pluralism, and civic values into the architectures of intelligent systems. This paper addresses the challenges posed by generative AI and data-driven infrastructures, arguing that ethical critique alone is insufficient. What is required is a systemic transformation encompassing education, governance, and culture. Cyber Humanism shifts the focus from protection to participation, from reactive ethics to dialogic, value-aligned design, emphasizing co-agency between human and algorithmic actors. Building on the Cyber Humanities Manifesto and aligned with European frameworks such as the AI Act, DigComp 3.0, and the Declaration on Digital Rights, the paper develops this paradigm across three strategic dimensions: (1) Reframing digital competence through cognitive sovereignty and reflexive agency; (2) Redesigning curricula and institutions as democratic infrastructures for human—AI co-authorship; (3) Operationalizing normative principles through participatory governance and cultural experimentation. The concept of algorithmic citizenship anchors this vision: a civic competence to critically engage with, co-govern, and reimagine the epistemic infrastructures of AI. The paper concludes by arguing that Europe is uniquely positioned to lead this transition by fostering a culture of dialogic design and epistemic co-authorship, in which intelligent systems are shaped deliberately, collectively, and with critical care.
