Elon Musk is known for his attention-getting tweets. But recently he seemed to suggest that Russian president Vladimir Putin might wish him harm. Tech billionaire Musk has been threatened by a Putin crony for sending communications technology to Ukraine. “For this, Elon, you will be held accountable like an adult,” the head of Russia’s space agency is quoted as saying. That prompted Musk to tweet, “If I die under mysterious circumstances, it’s been nice knowin ya.”
