How do companies such as Uber affect jobs and wages in the taxi industry? Dr Carl Benedikt Frey of the Oxford Martin School tells us what his new research indicates. Plus, we ask leading chemist Prof Clare Grey from Cambridge University whether Samsung's battery problems in its Galaxy Note 7 device suggest Lithium-Ion technology has reached its limits. And Zoe Kleinman visits London's Toy Fair to discover how tech is making its way into the latest games. Presented by Rory Cellan-Jones, with Jane Wakefield from the BBC Online tech desk, and special guest Tom Wiggins, deputy editor of Stuff magazine.
