Microsoft founder Bill Gates warned that political polarization in America could lead to civil war and “bring it all to an end.”

Gates’ comments came while speaking at this year’s Forbes 400 Summit on Philanthropy. The basis for his argument includes future election controversies.

“I admit that political polarization may bring it all to an end, we’re going to have a hung election and a civil war,” he predicted.

Gates also suggested that conspiracy theories involving vaccines and misinformation and his own role in their distribution are a contributing factor to the animosity felt across the country.
