A team of California scientists has just made a chilling announcement after intentionally infecting a human patient with an artificial intelligence-developed virus.
San Francisco-based AI research lab Radical Numerics says it has administered an artificial intelligence-engineered viral treatment to a human patient.
However, the lab admits that it infected the patient with the virus without publishing peer-reviewed findings or releasing clinical details for outside scrutiny.
Radical Numerics announced the experiment Tuesday in a technical report on its website, describing how it used AI to develop a treatment targeting a bacterial infection.
The announcement takes AI-designed biology beyond laboratory experiments and into human treatment, while leaving major questions about the patient’s outcome unanswered.
The viruses involved are bacteriophages, which infect bacteria.
The treatment is intended to attack harmful bacteria, rather than infect human cells.
But the company’s decision to withhold clinical information has drawn skepticism from outside scientists.
Human Treatment Announced Without Peer Review
Phage therapy uses bacteria-targeting viruses to combat infections.
Finding a virus capable of attacking a particular bacterial strain, however, can be difficult and time-consuming.
Radical Numerics says AI can transform that process.
