The rise, fall, and revival of the Caesar of Silicon Valley.

Elon Musk has cast himself as the savior of humanity, an altruistic force whose fortune is tied to noble pursuits from halting our dependence on fossil fuels to colonizing Mars. Once frequently heralded as a modern-day Edison, Musk has taken up a new place in the public consciousness with his growing desire to disrupt not just the automotive and space industries but the policies that shape our nation, even as his increasingly erratic personal behavior has raised questions about his stability and judgement.

Musk leads his companies from a bully pulpit, eroding guardrails and cutting through red tape whenever possible with little regard for the fallout as long as it serves his larger goals. As the scale of the wagers he makes with his fortune and concerns about his credibility have grown in recent years, he alternately seems to be in complete command or on the verge of a meltdown. Yet in the long run, he has only become wealthier, and now the stakes have risen. Thanks to astute political maneuvering, Musk is no longer limited to gambling with a company’s bottom line or the livelihoods of his workers; he is poised to apply his uncompromising approach to business to the foundational rules and regulations that hold our society together.
