We're in uncharted waters this week, as Ben and Barry are confronted with technology far beyond their understanding, otherwise known as our guest Andrew Somerville. An immersive theatre-maker and tech whizz (we don't really understand IT job titles...), Andrew's experience is brought to bear on the World's Worst Algorithms, with the boys tagging along gamely in his brainy wake. There's plenty to enjoy, from the story of Ada Lovelace, the chilling effects of living in online bubbles, and the man who can definitively tell us where Wally is.
