Remember how great the Internet was going to be?
It was going to unleash the collective wisdom of humanity. People were going to share ideas with people who they never would have encountered otherwise. Old ideas were to be challenged and tossed out if found wanting. All this sharing was going to make it easier for us to realize just how much we have in common with each other.
Unfortunately, the Internet just proved that crazy trumps wisdom, and facts fall in the face of lies.
The promise of all the good the Internet could do was there from the start. It was created by scientists as a way to make it easier to share information. It was assumed there was a way to tell good data from bad data. The more people who saw and assessed something, the more likely it was that flaws and mistakes would be discovered and corrected. That was the way it was supposed to work.
