Can we 3D-print a new heart to escape a family history of heart attacks? How about a smart 'wearable' that predicts diseases before you get sick? Technological innovations are promising to change our lives in innumerable different ways - but, are we ready?

Join comedian and tech-sceptic Rishi Budhrani on a technological odyssey as he puts these claims to the test, going beyond the hype to investigate the ethics of these innovations and how they might actually shape our lives.

As Rishi grills a series of scientists, futurists, engineers and programmers, we learn just how close we are to these technological dreams becoming reality, and whether we are ready for the new era they might usher in.
