Artificial Intelligence is used by Social Media?

Apparently the reason why we get notifications whenever a person messages us on Face Book or there is mostly topics interesting to us on the news feed is because they are using artificial intelligence. Face Book's system is an A.I that can recognize patterns based on how we interact with things and it delivers content that we find interesting in response. I think using artificial intelligence as a system increases a persons relationship with the social media platform because it caters to whatever the user likes instead of showing an advertisement that says ten interesting facts about ants. Also I think that Face Book is not the only social media platform using an A.I. Instagram's search feature shows a lot of pictures of people you do not follow. These pictures shown are based on whatever pictures you liked or what pictures the people you follow liked. In my opinion Instagram must us an A.I to do this because it is very similar to Face Book's A.I that shows only topics on the news feed that it thinks it would be interesting to you. Another platform that uses an A.I to cater to the user's interests is Twitter. Twitter introduced a feature called moments, it shows you news that you may find interesting just like Face Book's news feed which is why I suspect twitter is using an A.I as well. I believe that the more people use social media the more dependent they are on artificial intelligence which makes social media users post human. When people use social media they post pictures, tweets, and Face Book post which is stored information about themselves on the internet where everyone can see. Also people who want to stay connected with each other use social media websites to talk to each other. According to Katherine Hayeles as long as we are " “logged in” and using it, we are all using the same brain" (Jneiro, World press). Being logged in means that we all are sharing information  in some form with each other. Also In my opinion the use of the A.I. with Face Book no longer makes it a social network of people. Face Book is a network between humans and A.I because in order to find out if your friend posted something or if your friend messaged you the system's A.I has to notify you. Since the most an A.I can do today is recognize human patterns and deliver content a social media user finds interesting I think we are far away from Vinge's inflection point. Vernor Vinge is a mathematician and fiction writer who has an idea called inflection point. Inflection point is when artificial intelligence outsmarts humans. In my opinion the only way this can possibly happen is that if intelligent robots were able to learn engineering in an instant instead of going to school for a couple of years.
