There have been a few complaints from users of Google Photos about racist tags being applied to some photos.
This is an unfortunate mishap for Google, and one of those things that is always going to happen with any service that is attempting to display "intelligence".
I would say that while the words might be racist, the problem isn't one of racism, as I presume (and hope) that there is no intention by Google to be racist.
However, it does draw my attention to white privilege. As a white man, I'm unlikely to have my photos labelled with offensive terms as my boring middle-aged-man photos are going to form a large part of Google's test set. Also, boring English words like "gorilla" don't often take on an additional meaning that is offensive to boring middle-aged men.
It makes you think.
