Dunnow, May 18, 2017 : what? A neural network, without eyes, would do so in google. Because google photos needs it to offer more than just being a simple gallery. Dropbox does not analyze shit, in fact, Dropbox employees, that might need to manage user data, don't have access to the pictures but to a filename + exif data + hashed code. Also, if you are so paranoid of anyone entering your google photos account, just use a two step validation and solved. I certainly do not mind Google training his AI with my photos, as long as there's no human looking at them, there's no harm at all. Only gains, for me. The smarter their AI gets, the better I will be able to describe a picture for Google photos to return it to me from the +20k I have online already... "pictures of me and my dog during my birthday" the day you can do that without uploading a picture to the cloud to be analyzed by a neural network without human access, tell me. Tell me, what is wrong exactly on Google using my photos to do so? there's no human being looking at them. They do not have access to my pictures at all either. And all data used to train the AI (assuming they were using mine, which I doubt) is anonymous and invisible to every engineer working on it.
