"I wish we could be private with Tesla. It actually makes us less efficient to be a public company." - https://www.rollingstone.com/culture/features/elon-musk-inve...
The stock market news cycle is a constant barrage of criticism every quarter: commentary on whether they made some random analyst's projections, investors asking the same inane questions over and over... How many times has he given the "there's no point in giving you delivery estimates for specific months because the ramp will be exponential and small factors can change individual months by an order of magnitude" speech? I've heard him say that at least 10 times, and yet investors keep asking the same dumb questions every earnings call.
Which isn't really that huge of a time sink, but then people go and make a big deal out of that stuff in the press, "Model 3 production was supposed to be 5,000 by year end, and it's looking more like 500... Tesla suffers 90% crash in production rate! It's all over folks!" Even though Musk described this scenario two years ago, and said it was accounted for in their planning.
Now imagine he's trying to get to Mars and every 3 months he has to go in front of investors who are asking, "So, your orbital launch rate for this quarter seems to be 50% lower than projections, would you say that's more due to your incompetence or is it more that your business model is fundamentally flawed?"
He's not optimizing for quarterly revenue. He's not optimizing for revenue at all, he's optimizing to make something fundamentally new and valuable happen, and he's calculating that the value will come, although it's never clear what year. But a segment of public investors seem unable to accept that story.
