When facebook started making suggests for tagging I thought that it was really cool.  I now know that this was an early example of AI sometimes it would get it wrong, suggesting that my husband was my brother in law or that a friend was her sister. With time that I have discovered there are less errors and that the tag suggestions are more accurate.  I also noticed that my iPhone creates it’s own little video’s for me to enjoy or I can create my own by suggesting people or places as the categories. I think that this is a very clever and sophisticated use of data.
