Musk is frequently wrong with his timelines. That’s not a surprise to anyone. Even he has joked about his often unrealistic optimism with timeframes on multiple occasions. But I mean, most of us here are probably the same. Most CEOs I’ve worked with are quite poor at time estimates too. Come to think of it, I’ve never met a single human who is good at it. The problem is often unknown unknowns that you had no way to predict. I once had a project delayed by months due to a rare bug in the .NET CLR that just took a really long time to track down. I don’t know much about rocket science, but operating at the edge of known science and technology presumably has some difficult periods...
