Digital people: Mourners use artificial intelligence (AI) to digitally resurrect the dead
At a quiet cemetery in eastern China, bereaved father Seakoo Wu pulls out his phone, places it on a gravestone and plays a recording of his son.
They are words that the late student never spoke, but brought into being with artificial intelligence.

Ultimately Wu wants to build a fully realistic replica that behaves just like his dead son but dwells in virtual reality.
"Once we synchronise reality and the metaverse, I'll have my son with me again," Wu said.

Some Chinese firms claim to have created thousands of "digital people" from as little as 30 seconds of audiovisual material of the deceased.
Experts say they can offer much-needed comfort for people devastated by the loss of loved ones.
But they also evoke an unsettling theme from the British sci-fi series "Black Mirror" in which people rely on advanced AI for bereavement support.

The accounting and finance student, keen sportsman and posthumous organ donor "had such a rich and varied life", said Wu.
"He always carried in him this desire to help people and a sense of right and wrong," he told AFP.
