It's definitely been a net positive for the most part.
But in the last few years... There has been a significant rise in fake information, A.I driven content and conspiracy theories. (I.E. Flat Earth, Anti-Vax, Anti-Climate change, Chemtrails and more) and unfortunately people have proven to be far to stupid to identify the fake information associated with those and in-turn they attempt to spread it as fact, whilst being unable to be convinced (even with evidence) otherwise.
They exist in their own echo-chamber.
So yes, the largest repository of information known to man has been a general net positive, but socially it's starting to be destructive... It will be interesting to see how the next 10 years will go, whether fake information and conspiracies will continue to dominate or not.
