When not even video is proof anymore: artificial intelligence is changing the concept of truth in Justice

oglobo1 September 2026 at 11:39

For decades, photographs, voice recordings, and videos were treated in courts as the ultimate proof of truth. If there was an image, something had happened. If there was an audio, someone had said that. This certainty, according to lawyer Jonatas Lucena, is crumbling and Brazilian Justice is beginning to feel the direct impact.

The question that any lawyer, expert, or magistrate needs to ask when faced with audiovisual evidence today is no longer "what does this video show?", but rather: did this really happen? Artificial intelligence technology allows for increasingly realistic synthetic content to be created, putting the reliability of audiovisual evidence at risk.

The National Data Protection Authority (ANPD) did not leave this observation merely in the realm of intuition. In July 2026, the agency published Technological Radar No. 6, a 163-page technical document entirely dedicated to deepfakes, which maps how synthetic content generated by artificial intelligence has been used in financial scams, among other fraudulent uses.

Anthropic says new version of AI model Fable is cheaper and better at programming

Anthropic is launching Fable 5.1, a new version of its artificial intelligence model that promises to be cheaper and better at programming and scientific tasks. According to the company, the model is more competent at long and complex programming tasks, such as software projects and code reviews that require working across an entire application's codebase. The new version also offers better support for scientific work, including designing experiments, simulating results, and interpreting complex diagrams and tables. Anthropic claims the improvements were made in response to customer feedback, at a time when companies are seeking to justify and control the costs of using artificial intelligence.

Study shows that AI is changing the way work is designed

A study analyzes how artificial intelligence is transforming work design, identifying four possible scenarios for the next decade. The authors conclude that AI should significantly alter tasks and professional functions, but without causing a generalized employment collapse, suggesting a reconfiguration of the labor market rather than massive worker replacement.
