The factual core is true: on 19 March 2020 Musk tweeted that based on current trends there would "probably" be close to zero new US cases by the end of April. That was badly wrong — cases were tens of thousands a day by then, and COVID went on to kill over a million Americans. He deserves criticism for a confident bad call, and several of his pandemic takes aged poorly. But "proves he's a crank" is a leap. Early-2020 forecasting was wildly uncertain across experts and institutions, the word "probably" hedged a guess, and one wrong prediction doesn't negate verifiable achievements like landing reusable rockets or building the best-selling car on Earth. Tesla also pivoted fast to build ventilators and testing capacity. A wrong prediction is a wrong prediction — not proof he's a fraud on everything else.
