For decades, practically every classroom in the United States had one thing in common: a big, bright overhead projector at the front of the class. How it got there is a story that takes hundreds of years, and a war or two, to explain. David Pierce is joined by The Verge’s Jake Kastrenakes and Stanford professor Antero Garcia to learn about where projectors came from, how they took over education, and why they eventually faded out.

Instead, it was a portal to a big new idea about computers. David Pierce is joined by The Verge’s Nilay Patel and MKBHD’s Marques Brownlee to explain the history of ChromeOS and Chromebooks, and figure out whether Google’s approach to computer hardware was the right one.

The idea was big, exciting, and inspiring: What if we could get every kid in the world access to a computer? For a bunch of thinkers and executives in Silicon Valley, it felt like the way to fix everything. But the One Laptop Per Child initiative, and the XO-1 laptop designed to be given away, were both more complicated than anyone expected. David Pierce is joined by The Verge’s Adi Robertson and tech journalist David Imel to figure out why OLPC didn’t work, whether there’s anything to learn from the XO-1’s innovative design, and whether this kind of computer giveaway could ever actually succeed.

From The Vergecast, this episode takes a look back at one of the earliest chapters in the history of AI. Before Alexa and Siri, there was ELIZA. The first chatbot ever was the creation of a man named Joseph Weizenbaum, who built the bot almost as a magic trick — and then couldn't believe how many people fell for it. David Berry and Mark Marino, two members of a team dedicated to restoring and understanding ELIZA, explain how Weizenbaum created the virtual conversant, why he came to regret it, and what ELIZA can teach us about life in the AI age.

David Pierce is joined by Eater editor Melissa McCart and champion barista and author Morgan Eckroth to discuss the whole history of Keurig, from its creation in a Boston apartment to its invasion of seemingly every house, doctor's office and conference room in the US. Keurig was certainly a success, but was it a good thing? For coffee, for the world? That's more complicated. We’re also on video! Check us out on YouTube.
