Elon Musk beat out Jeff Bezos, Mark Zuckerberg and Steve Jobs as the most admired tech leader among 700 founders surveyed by VC firm First Round Capital. Twenty-three percent of founders wrote in the SpaceX and Tesla CEO’s name when asked whom they admired the most; 10 percent said Bezos, 6 percent said Zuckerberg and only 5 percent of respondents wrote in Jobs.

(That’s a lot compared to the mere 1 percent who wrote in Facebook’s Sheryl Sandberg — the most cited female among founders.)

The survey was published on Thursday just weeks after Tesla reported a relatively stellar quarter for only the second time in its history as a public company. Musk is certainly nothing if not ambitious, but it is exactly his lofty ambitions that often get the better of him.

Tesla has a track record of consistently missing production and shipping deadlines for its vehicles (see: Example A, example B). The company has since ramped up its production and says it’s still on track to meet its goal of shipping 50,000 cars in the second half of 2016. But Musk has another aggressive goal he set for himself: Begin production on the upward of 300,000 preordered Model 3s by the end of 2017.

At the unveiling earlier this year, Musk said he was confident Tesla will be able to begin production as planned. But it’s the first time the company has had to produce and distribute a vehicle at this volume. Tesla’s luxury vehicles — the Roadster, the Model S and the Model X — have all been low-volume businesses and intentionally so.

Even when preorders were just at 198,000, Musk suggested the company will have to change how it plans to build the car:

Definitely going to need to rethink production planning... — Elon Musk (@elonmusk) April 1, 2016

But forgetting Musk’s earthly ambitions, the SpaceX CEO wants to begin colonizing Mars by 2024. In fact, Musk hopes he can send the first unmanned crew to the red planet by 2018. But just weeks after the executive revealed some of the details of how he planned to do that, one of SpaceX’s rockets exploded and the company is still not sure why.

The company did just announce plans to launch on Dec. 16 the first rocket since the explosion.

That said, SpaceX has been striking deals with NASA left and right to do things like launch satellites that will monitor the earth’s surface water and, in turn, climate change. It’s a doubly important task for the company because for one, Donald Trump wants to defund any climate change efforts and two, the money from the NASA deal could go toward funding Musk’s Mars ambitions.

This is all to say, sure, Elon Musk is ambitious — admirable, even. But like all mere mortals, he has his failings.
