Anthropic's watermarking system aims to comply with the EU AI Act but has limitations, including concerns over text quality and the inability to confirm authorship. The company states, “In internal testing, we’ve seen no impact of watermarking on the content, level of creativity, or readability of Claude’s text.”1234

However, users fear it may degrade outputs and label their work. The watermarking can’t be applied to small text samples or specific code fragments, as fewer word choices limit its effectiveness.

In a broader context, Pope Leo XIV's encyclical, “Magnifica Humanitas,” warns that AI technologies could exacerbate historical injustices, including slavery. He emphasizes the need for ethical oversight, stating, “Justice demands that we prevent the emergence of new forms of exclusion and deprivation of freedoms.”5

Leo argues that AI's development should not replicate past power imbalances, urging a diverse approach to technology that avoids a corporate monoculture. He highlights the risk of dehumanization, stating, “The risk of dehumanization... is an ancient and ever-new temptation that today takes on a technical guise.”

The encyclical calls for vigilance against the potential for AI to create “second-class” human beings, echoing the historical legacy of slavery and colonialism, and advocating for justice and fraternity in technological advancement.

Key Insight
“Anthropic's watermarking can't trace text to a specific person or chat, and it fails on small samples or code fragments. The pope's encyclical 'Magnifica Humanitas' makes six claims, including that AI in weaponry lowers the moral threshold of conflict.”
