Social media was already isolating people. It is being sped up by the use of AI bots (see dead internet theory). These bots are being used to create chaos in society for political purposes, but overall it's increasingly radicalizing people and as a result further isolating everyone.
AI isn't eroding college institutions, they were already becoming a money grab and a glorified jobs program. Interpersonal relationships (i.e. connections) are still present, I don't see how AI changes that in this scenario.
I am not a fan of how AI is shaping our society, but I don't place blame on it for these instances. It is in my opinion that AI is speeding up these aspects.
The article does highlight one thing that I do attribute to AI and that is the lack of critical thinking. People are thinking less with the use of AI. Instead of spending time evaluating, exploring and trying to think creatively. We are collectively offloading that to AI.
