"Laughing with Hitler" is a journey into a supposedly humorless time. In the Third Reich, however, the Führer and his Nazi bigwigs were laughed at. The political jokes of the Hitler years were a barometer of true public opinion. But those who dared to make jokes critical of the regime lived dangerously. In the early Nazi era, Hitler jokes were punished as "insidious", during the war even as "undermining of military strength" and the penalty was the death penalty! The conflict with the Nazi authorities ended more mildly for other pranksters: the cheeky cabaret artist Werner Finck was deported to a concentration camp, but was released again.

Culminating in his sad death as remembered by one of his sons and one of his daughters, the film looks at Barry's childhood, his time in prison, and his decision to go into music and thereby change his life.

Professor Jim Al-Khalili looks at how we have created machines that can simulate, augment, and even outperform the human mind - and why we shouldn't let this spook us. He reveals the story of the pursuit of AI, the emergence of machine learning and the recent breakthroughs brought about by artificial neural networks. He shows how AI is not only changing our world but also challenging our very ideas of intelligence and consciousness. Along the way, we'll investigate spam filters, meet a cutting-edge chatbot, look at why a few altered pixels makes a computer think it's looking at a trombone rather than a dog and talk to Demis Hassabis, who heads DeepMind and whose stated mission is to 'solve intelligence, and then use that to solve everything else'. Stephen Hawking remarked 'AI could be the biggest event in the history of our civilisation. Or the worst'. Jim argues that AI is a potent new tool that should enhance our lives, not replace us.
