Developer conferences aren’t just a chance for tech companies to incentivize app makers and show off the latest tricks and tools in software. The events also present an opportunity for companies like Facebook, Microsoft, and Google to assure the public that they are on it when it comes to issues like privacy, openness, and also, privacy. And companies often use the giant keynote stage to show off futuristic demos involving augmented reality, artificial intelligence, and assistive technologies. How much of this is reality–not the virtual kind–and how much is simply lip service? The Gadget Lab team discusses on this week’s podcast.

Recommendations: Arielle recommends checking out BTS, if you haven’t already. Lauren recommends Emily Dreyfuss’s compelling interview with Melinda Gates. Peter recommends this percussive therapy instrument, no really.
