Meredith’s work has shaped global AI policy and shifted the public narrative on AI to better recognise the surveillance business practices and concentration of industrial resources that modern AI requires. As President of the non-profit Signal, the secure messaging service used by journalists, activists, whistle-blowers and soldiers, she has fought against government attempts to break encryption. She joins us to discuss encryption and the government’s fight to end it, AI regulation, big tech surveillance, and what the US Presidential election result means for all of it.
