COURTNEY MARES, National Catholic Reporter; Meet the Silicon Valley priest advising tech companies on artificial intelligence ethics

"Fr. Brendan McGuire used to be a Silicon Valley technology executive. Now he's hearing their confessions. Today, the Irish-born pastor of St. Simon Catholic Parish in Los Altos, California, is helping to shape the moral conscience of the artificial intelligence industry.

Earlier this year, he was among the faith leaders invited by Anthropic, the AI company behind the chatbot Claude, to advise on the creation of an ethical framework to govern how the AI system handles complex moral questions.

McGuire, 60, holds engineering and computer science degrees from Trinity College Dublin and completed Stanford University's executive business program. He spent years in Silicon Valley as a technology executive before leaving it all behind to be ordained a priest of the Diocese of San José 26 years ago...

"I came from the industry," McGuire told OSV News. "My heart's never left it, but my heart is really with the Lord."

"I've always felt my role was to bridge those two worlds together," he said...

"Capitalism needs human guidance. And this is the human guidance the pope is asking for," he told a group of journalists after Anthropic co-founder Chris Olah spoke at the Vatican press conference with Leo to present the encyclical.

The priest is also skeptical of industry self-regulation. Transparency, he argued, is the necessary first step toward accountability.

"Transparency leads to accountability, and accountability leads to trust. And with trust we'll have responsible AI. But we can't get there without transparency," he said. "If we don't know how these things are being developed and what they're doing, then how could we regulate them? We can't."

Still, McGuire resists both techno-utopianism and techno-apocalypticism.

"There are those who … think it's going to destroy humanity. And then there are those on the other end who think it's going to be the great savior of humanity," he said.

McGuire said that he sits in between these two extremes."
