Rapper Will.i.am says technology will revolutionise the way people live 20 years from now.
He has become intrigued by 3D printing and believes the technology will change the way all humans live in the future, enabling people to create their own food, reports femalefirst.co.uk.
He said: "It will revolutionise society. To eat beef and wear leather, you need a lot of land and water for cows. In the next 20 years, we'll be able to print beef and leather instead. It might sound like science fiction but right now, I can take you to a factory in Brooklyn that prints out leather."
