Facebook will lose 80 percent of its users over the next three years, according to a study from Princeton University.
CBS This Morning reported that the percentage made up 952 million people.
The study compared the rise of social media to infectious diseases.
However, Scott Stein, a senior editor at CNET, told CBS that there is room for disagreement.
"I think there are some things that spread and most people have seen them," explained Stein. "There's still a billion plus people that use Facebook and is it about getting new users or is it about eventually just growing the interaction with the users you have? You can't sign up that many more people on the planet."
Because the internet is continually changing, Facebook will need to figure out how to evolve with it, Stein said.
The study cited search data from Google to predict the trend.
Facebook fired back in a post called "Debunking Princeton". It said researchers should have used actual engagement trends.
The post said that by following the university's method for the study, Princeton itself may be in danger of disappearing entirely by the year 2021. The social media giant posted a graph showing a sharp decline in "likes" related to Princeton's Facebook page. That graph can be viewed here.
It also said that Google trends for the school have declined over the past several years.
Whether Princeton's prediction plays out remains to be seen. Facebook admitted on Wednesday that it is losing its teenage users to boredom.
