There is tremendous value in this podcast. Many histories are linear stories of how we got to today, but Sean Haas goes further by exploring many of the dead ends. Those diversions are essential if you want to understand the why, and not simply the how.

It also manages to strike a reasonable balance between being an easy listen while going adding some technical depth. For example: you aren't going to learn enough to build your own mercury delay line, but you are going to have a rough idea of how it worked and what the limitations were. It is as much a history of technology as it is of the people behind it.
