Geoffrey Hinton's work laid the foundation for today's artificial intelligence systems. His research on neural networks has paved the way for current AI systems like ChatGPT.

In artificial intelligence, neural networks are systems that are similar to the human brain in the way they learn and process information. They enable artificial intelligence to learn from experience, as human beings would.

But Geoffrey Hinton has warned that machines could one day outsmart humans. He has even warned that autonomous weapons could be active on the battlefields of the future. In this final episode of 25 Years of the 21st Century, Matthew Syed interviews Professor Hinton.

Historian and author Margaret MacMillan and Baroness Joanna Shields also join Matthew in discussion. Baroness Shields has been working in the field of technology for forty years, holding senior roles at both Google and Facebook. She was the UK’s first Minister for Internet Safety and Security. She’s also a Conservative life peer in the House of Lords. Does she agree with Geoffrey Hinton's concerns for the future?

For 25 Years of the 21st Century, is this the age of artificial intelligence?
