For once, I agree with a billionaire.

Social Media is a perfect gateway to push fake news down the throat of all readers. It indeed is cancerous.
With the rise of AI and Bots. Fake news will be evermore a greater problem that has the potential to ignite fear, uncertainty and doubt. It can fool even the educated.
So... if WW3 happens... social media may play a part in causing it.
