How does the 'What3Words' algorithm work, what is it used for and what problems does it have?

The article discusses the What3words algorithm, which divides the world into 57 trillion squares, each measuring 3x3 meters and assigned a unique address made up of three random words. This system allows users to easily share locations in a way that is practical and memorable. It's especially useful in areas where traditional addresses are insufficient or nonexistent. The article also goes into how the algorithm employs different techniques to ensure that the words used are easy to remember and pronounce, enhancing communication. In addition, it addresses security and privacy issues, emphasizing that despite the use of words, there is minimal risk of sharing too much personal data. In short, What3words is an innovative approach to location that transforms how we identify places on a map.
