We must be wary of the power of AI Letters

In his interesting opinion article (Robots sacked, screenings shut down: a new movement of luddites is rising up against AI, 27 July), Ed Newton-Rex misses one of the most serious concerns about artificial intelligence: its surveillance potential. Governments have always spied on their subjects/citizens: technology multiplies their powers of spying. In his novel 1984, George Orwell had the authorities install a two-way telescreen system in every party member's home, and in all workplaces and public spaces. This allowed Big Brother to monitor individuals' actions and conversations, while he himself remained invisible. Today's digital control systems operating through electronic tracking devices and voice and facial recognition systems are simply Big Brother's control devices brought up to date.
