In this episode we interview Professor Andrej Zwitter to talk about the good, the bad and the ugly of big data. In a world where 2.5 quintillion bytes of data is being created on a daily basis, there is a need to understand how big data can and is being used.

However, the lack of regulation on how big data is being utilised in both the public and private sectors for political campaigns and product marketing is a big concern. In this episode we find out what can be done.
