On one hand the Dropcam
is constantly uploading video and audio of you and storing it in the cloud for extended periods of time, even when you're home.
On the other hand, the Echo Look only uploads photos when you ask it to, and AFAIK doesn't store them, but everyone is freaking out because it could upload photos whenever it wants.
Sure, HN doesn't see the value in a Look, but it is clearly less invasive than a Dropcam.
