Tim Harford has a second round of his podcast series on the BBC, 50 Things That Made The Modern Economy, which rolling out new episodes weekly. The first season's episodes were collected into book form, where the new second season is extending the list of short stories about technologies that have changed how people live and what they do.
We highly recommended the series, where last week's episode on the humble electronic spreadsheet is a standout among all the episodes of the entire series, which has included tales of items such as the Billy Bookcase and the Index Fund.
What makes the 11-minute episode stand out how it ties into modern concerns of how jobs change when new technologies make old ways of doing things obsolete. What can happen to people when robots can take over their jobs?
