I published a piece in Slate this afternoon on the heels of Apple announcing its new Vision Pro AR/VR headset (“Apple Is Ignoring Something Big About Augmented Reality,” June 8). For that piece, I wrote about watching Apple’s announcement through my own experience teaching with Google Glass in the classroom almost 10 years ago. I am not dismissive of the entire product category. There were some really interesting gaming and information layer options Glass had that I could see being popular. My class also did some great work with video on the device.
