The New York Times did a study, analyzing nearly 70,000 social media posts from Elon Musk over the past 15 years, 19 Tesla earnings call transcripts, and all the promises he made across his six companies. The results: Only 19% of promises were delivered on time. 33% of promises were unachievable. A staggering 35% of promises remain unfulfilled. Musk is a big liar full of empty talk, only fooling Tesla fanboys.
