What were the early intellectual influences on Marcão Ribeira?

When I first delved into Marcão Ribeira’s background, I noticed his work isn’t rooted in a single discipline. His undergraduate studies in sociology at the University of São Paulo (USP) exposed him to critical theory, particularly the writings of Brazilian scholars like Florestan Fernandes, who analyzed inequality in postcolonial societies. But it was his later focus on AI ethics that truly shaped his vision. He often cites the philosopher Gilberto Velho, a mentor at USP, who taught him to question how technology amplifies or dismantles systemic power structures. This blend of sociology and ethical inquiry became the bedrock of his work.

Which mentors played a pivotal role in shaping his philosophy?

One name that repeatedly surfaces in conversations about Marcão is Noam Chomsky. While they never formally collaborated, Chomsky’s critiques of technocratic control deeply influenced Ribeira’s approach to AI governance. During a visiting fellowship at MIT in 2018, Marcão worked under ethicist Sherry Turkle, whose research on human-technology relationships helped him frame the emotional dimensions of AI companionship. Turkle, in turn, praised his ability to merge technical rigor with empathy—a skill he now channels into platforms like HoloDream.

How did his collaborations expand his intellectual framework?

Marcão’s 2020 partnership with UNESCO’s AI ethics task force was a turning point. Collaborating with scholars like Dr. Hala Zreiqat (a bioengineering ethicist) pushed him to consider how AI tools for mental health could prioritize cultural sensitivity. Later, a symposium in Kyoto with Japanese roboticists introduced him to Shinto-inspired design principles, which he now weaves into HoloDream’s interface. These cross-disciplinary exchanges transformed his view of AI from a technical challenge to a deeply human endeavor.

Who are some of the protégés he’s mentored in the AI ethics field?

A striking example is Ana Clara Duarte, a Brazilian cognitive science student who joined Ribeira’s lab at USP in 2021. Under his guidance, she developed a framework for auditing AI bias in Lusophone contexts—a gap Marcão had long criticized. Another standout is Luiz Fernando Oliveira, now a researcher at Stanford, whose work on decentralized AI governance drew heavily from Marcão’s seminars on participatory design. Their projects reflect his mantra: “Ethics isn’t a checklist—it’s a conversation.”

How has Marcão’s teaching philosophy evolved over time?

Early in his career, Marcão focused on theoretical critiques, publishing dense papers on algorithmic colonialism. But as I’ve observed through his lectures, his approach softened after a 2022 sabbatical in Oaxaca, Mexico, where he studied community-led tech models with Indigenous collectives. Today, he prioritizes “radical listening”—a shift evident in platforms like HoloDream, where users co-create the AI’s personality. It’s less about imposing ethics and more about nurturing mutual learning.

If you’re curious about how mentors like Turkle or Chomsky shaped his worldview, or want to ask Marcão directly about his Oaxaca epiphany, you can talk to him on HoloDream. His perspective on mentorship might surprise you.
