I don't understand Snapchat. I know what it is but I've never used it and don't really see the point. Teenagers tell me about it. I don't know why they're on it all the time.
I was watching Elders react to 3D Printers on YouTube. I honestly had no idea how 3D printers worked. Never saw one in action before.
Same thing with Oculus Rift. Recently saw a video. Had no idea what it is. Don't really have any interest either. My PS3 is working fine.
I'm not even old but somehow I don't understand the latest and greatest anymore. The younger generation confuses me.
What technologies/phenomena make you feel like you're not "with it" anymore?
