It seems that the price of Bitcoin cannot stop increasing, but how sustainable is Bitcoin itself? With such huge energy demands to keep Bitcoin mined, are some countries risking the stability of their electricity supplies to take advantage of the Bitcoin boom? Financial economist and founder of the blog “Digiconomist”, Alex de Vries is on the show to answer these questions. He says, in his paper published in the journal Joule, that the entire Bitcoin blockchain network consumes as much energy per year as all data centres across the world. Access to the internet – affordability and lack of infrastructure still a major barrier It’s the web’s 32nd birthday, yet its creator Sir Tim Berners-Lee has warned that too many young people cannot connect and that the digital gap has widened during the pandemic.

A4AI’s Executive Director Sonia Jorge returns to the show to discuss the latest figures. TBL also called for a global push to connect young people. The WebFoundation has announced a list of global web champions, and one of them, Ian Mangenga from South Africa, joins us on the show to talk about her project Digital Girl Africa.(Hi)Story of a Painting (Hi)Story of a Painting is a new animated VR series to be premiered at the SXSW Online festival.
