I think it falls a little bit of in a grey area here. Social media the way it started had SO MUCH potential, but then it had to be made addictive (and guess whose decision that was, hint, not exactly the user's). And on top of that add how our lazy nature made it sooo easy for fake news to spread and exacerbated the problem in ways that we just didn't expect.

Now to answer with my opinion here, I do think that social media has great potential, thing is that as everyone is given "a voice", some people just haven't earned it. Just see how easy it is to spread fake stuff around. I wish there was a way for people to learn how to not fall prey to these tactics and then Social Media would be a different place, but alas no one is taught how to properly "go online".

So yeah, while it is kind of cancer, it is a preventable one.
