In this photo taken on May 5, 2026, Scientific Systems Intergration Manager Justin Bourke inspects a CL1 unit containing cortical and hippocampal cells on a cell culture plate as they are placed in servers where they are available to study via the internet, at Cortical Labs' Physical Containment Level 2 (PC2) laboratory in Melbourne. Australian researchers have trained lab-grown brain cells on a silicon computer chip to play the nineties shooter "Doom" and say they are just scratching the surface on what the neurons could be capable of doing.

British artist Harry Yeff (also known by his stage name Reeps100) and British-Canadian soprano Patricia Auchterlonie (R) perform on stage during a preview rehearsal of his piece "transference" which uses artificial intelligence (AI) to render the human voice, at the Royal Opera House in central London on May 29, 2026. The RBO/SHIFT is a new festival that looks at the intersection between opera and technology. (Photo by Henry NICHOLLS / AFP via Getty Images)
