How do you fight a surveillance state?

We have never lived in a more closely monitored world. Facial recognition technology is being rolled globally, including across the UK. Data can be acquired without a person’s knowledge, let alone their consent. There is a creeping paranoia and concern among human rights experts that advanced surveillance technology could fall into the wrong hands.

We speak to Lokman Tsui, a tech expert and university lecturer in Hong Kong, who is living the midst of an increasingly violent protest movement paranoid about surveillance. We also catch up with Newsnight’s Gabriel Gatehouse, who has just got back from Hong Kong, where he met the young people willing to sacrifice their lives to fight against what they believe to be the oppressive application of technology from mainland China. They both explain why there are lessons from Hong Kong for all of us about the kind of technological future we want to live in.
