The Beatles' 'final' record: Should we bring singers back from the dead?

With the news of a 'final' record from The Beatles, and the development of AI voices, holograms and "raves beyond the grave", where should we draw the line, asks Arwa Haider.
"I think we're actually on the cusp of something exhilarating and terrifying… it's an alien life form." When Bowie voiced these thoughts in a 1999 interview, he was greeting the creative dawn – or potential cataclysm – of the digital age. His words seem even more spookily resonant several years after his death (the Starman left this world in 2016). The music industry remains in a state of flux, and tech continues to connect realms – and maybe even raise the voices of long-departed singers.
