Musk attributes it to Churchill though I don't think anybody has found any evidence that the prime minister ever said it. The earliest evidence anybody can find of the phrase came from the 90s.
Maybe Geoff Loftus can provide a reference so the world can stop looking. Just because its in an article from a contributor to Forbes doesn't make it factual. It just means he thought Churchill said it when he wrote his article. Musk did the very same thing.
