Sci-fi author and digital rights activist Cory Doctorow talks about a coming 'war on general purpose computing', which could have far reaching consequences for our society. In the race to regulate the internet, governments of all persuasions are looking at ways to control how our digital devices work, and to narrow their functionality. We also get a tour of the Think Ahead exhibition in Melbourne. (Our apologies. In our original program we incorrectly described Cory Doctorow as a US blogger. He is in fact Canadian. We’ve updated the podcast to correct that mistake).
