Luckily I don't need to generalize the Internet to be good or bad, I only need to determine whether the good it brings to my life personally outweighs the bad.

I don't have an exact answer to that, but what I do know for sure is that the good has been on a downward trajectory, and the bad on an even steeper upward one, for years. Even if they haven't actually crossed yet, it seems only a matter of time before they will.
