Should we worry AI will create deadly bioweapons? Not yet, but one day

Should we worry AI will create deadly bioweapons? Artificial intelligence promises to transform biology, allowing us to design better drugs, vaccines and even synthetic organisms for, say, eating waste plastic. But some fear it could also be used for darker purposes, to create bioweapons that wouldn't be detected by conventional methods until it was too late. So, how worried should we be? "AI advances are fuelling breakthroughs in biology and medicine," says Eric Horvitz, chief scientific officer at Microsoft. "With new power comes responsibility for vigilance." His team has published a study looking at whether AI could design proteins that do the same thing as proteins that are known to be dangerous, but are different enough that they wouldn't be recognised as dangerous.
