Presenters Leo Johnson and Timandra Harkness discover what impact technology will have on expanding - or contracting - opportunities for different sections of society in future. From a tough council estate in north London, to the labs at Harvard University developing tools to expand and augment human brain power, FutureProofing investigates how technology is set to alter the landscape of opportunity for millions in the 21st century. Algorithms could discriminate far more against different sections of the population, just as the network effects and low costs of entry might create huge new openings for people previously excluded from economic success. And the opportunities opened up by a revolutionary brain implant being developed in the USA could transform everyone's life chances in future. Producer: Jonathan Brunert
