Artificial intelligence has become one of the defining technologies of the modern era, reshaping everything from business to medicine. Scientists at Stanford University have successfully used artificial intelligence to design 16 new functional viruses that do not exist in nature, according to the Daily Mail. Sixteen of the AI-designed viruses successfully destroyed E. coli, demonstrating that artificial intelligence can generate viable viral genomes capable of functioning in the real world. However, he said the study demonstrates that artificial intelligence can successfully design viable viruses that have never existed naturally. “We should worry more about who has access to these powerful biological AI tools,” he told the Daily Mail.
