I think this is a poor idea. If it were to take off, you can be sure there would be loads of spoof sites popping up mascaraing as facebook drawing in vulnerable people.
For all the tech giants are harping on about AI and how it is going to take everyone's jobs in the next 20 years, all the AI I have seen is generally cr@p. I did a Google photo search of my photos today looking for pictures of canals. Amongst the odd picture of a canal, there was a picture of a bench, lakes, rivers, woods - basically more "not" canals than canals.
It is impressive to an extent, but if you were judging a small child on it being able to spot pictures of canals, you would definitely put the Google child in the category of someone who had a severe learning disability.
