Pak migrant seen telling Danish man, 'You'll be exterminated, we've 5 kids'; Musk reacts

World's richest person Elon Musk has reacted to an undated video purportedly showing a Pakistani migrant telling a Danish man that "you'll soon be exterminated", saying, "His math is correct." "We have 5 children, while you have 1 or 2. In 10-15 years, there will be more Pakistanis than Danes," the migrant apparently said in the video.
