Jaron Lanier, who popularised the virtual reality concept in the early 1980s, said that in rush to forge a new age of collectivism, we risk losing individual identities and dumbing down our understanding of the world.
He told BBC World Service's Culture Shock that his main problem is that in places like the blogosphere or the online encyclopaedia Wikipedia, people no longer treat or respect each other as individuals.
"We have these designs on the internet where a whole bunch of people work together anonymously - a mob, in my opinion - in order to do something," he said.
"They actually take on the emotional quality of a mob - they become mean, they tend to insult each other a lot more than they would if they knew who each other were. In my opinion, this is an example of a design that isn't so great."
