I think the world would be lost.
The internet is a mirror of the world, but up close in your face.
Online one can learn things more easily, donate to tzedaka more easily, find out information and attend important events, shiurim..etc.
Online one can also more easily, chas veshalom, stumble into terrible things.
That being said, the internet is a more personal and convenient way to come across the same things you can find on Main Street, Wall Street, Easy Street, etc…..
It is more demanding on us to use our discretion, but not so different from the challenges in the world at large.
