Tim Berners-Lee is one of the men who has changed the world. Born in London in 1955, he is a computer engineer and also a professor at the Massachusetts Institute of Technology (MIT). He is known worldwide as the creator of the World Wide Web (www), the revolution that allowed communication between a client and a server for the first time and, in doing so, changed the history of the internet. In a conference at the Talent Arena at the Montjuïc Fair, the space for digital talent promoted by MWCapital alongside Mobile World Congress, Berners-Lee criticized the massive use of addictive algorithms on social media and argued that some countries should ban social networks or phones in response.
