Tech Tent 66: Money and Power

The European Union accuses Google of abusing its dominant market position in search to promote its own shopping service. We hear from a complainant and get a counterview from James Waterworth from the industry body CCIA. As "Moore's Law" on the pace of development in computer chips turns 50 years old this weekend, we speak to co-authors of the book "The Second Machine Age" Erik Brynjolfsson and Andrew McAfee from MIT on whether future progress will depend more on software than silicon. Plus, a new cash machine that's claimed to be more secure, and more cost-effective for developing countries. And Zoe Kleinman tries to use Bitcoin in the Isle of Man.

Presented by Rory Cellan-Jones, with special guest Leo Mirani of Quartz.
