Former Facebook exec fears robots will destroy society within 30 years

A former Facebook executive has quit his job and now lives as a recluse in the wilderness — because he is convinced that machines will take over the world.

Antonio Garcia Martinez worked as a project manager for the social media giant in Silicon Valley but became terrified by the relentless march of technology.

He reckons that machines will have taken half of humanity’s jobs within 30 years, sparking revolt and armed conflict.

So he quit his job, fled his home and now lives in woodland north of Seattle with a gun for protection.

He spoke to new two-part BBC2 documentary “Secrets of Silicon Valley,” which explores the growing influence of the tech hub on global development.
