I think I'm most concerned about the convergence of AI with social media, or possibly deep fakes and their ability to create disruption. Both are driven by the same fear - tribal/herd mentality and the inability of so many to decipher real vs fake or to be easily influenced.
My fears are mostly generated by the feeling that far too many people are gullible, believe everything at face value, and/or are easily influenced by their social network or media networks. It doesn't matter their political alignment or religious beliefs, echo chambers have become huge with social media and cable tv on every side.
Facebook groups are probably the best example of something that creates a pen of like-minded sheep, echoing the same false view on whatever is going on. "Influencers" in society today are nothing more than snake oil salesmen of the old days - praying on those easily swayed or already in a corner of the ring, and these two examples work together in so many hurtful ways already.
With the tribal nature of our society, and the tinderbox we seem to be standing on, technology is at a point - or will be in 3-5 years - that it will be exploited in such a way that it's impossible to tell what's reality.
