ISSUE 50! Round-up of the top articles so far - 

The new oil
Data is giving rise to a new economy - but unlike any previous resource, there is a “disincentive to trade” as data can be duplicated and used for other purposes. But if data “remains stuck in silos”, most of the value “may never get extracted
–> Information gets more valuable when it is shared, to the extent that disconnected data (due to silos and ineffective collaboration) costs organisations $140 billion a year.
Having a competitive advantage is now dependent on accessing huge stockpiles of data (alongside having strong consumer data protection). 
Companies need a solid foundation of high-quality data to make their AI effective. If AI is fed garbage, the output will be the same –> machine learning will “only ever be as good as the data”.

The Royal Free hospital broke the law when it gifted 1.6 million patient records to DeepMind. Elizabeth Denham: “it’s not a choice between privacy and innovation” - it needs to be done correctly and transparently.
The ICO fined 11 big UK charities for swapping and selling donor lists. The charities were “wealth screening” supporters and identifying new ones by piecing together personal info from other sources. A number of charities also created a massive pool of donor data for sale.
