Many of today’s top CEOs are known for their unconventional schedules, behaviors, and beliefs.

Elon Musk offers a particularly intriguing insight into the universe and our current world. Here are some fascinating concepts he has shared.

Martian Governance: Musk has pondered extensively on the logistics of frequent travel to and from Mars. Additionally, he has contemplated the structure of a potential human government on the red planet. Musk has suggested that a Martian democracy should be direct rather than representative, stating, “So it would be people voting directly on issues. And I think that’s probably better because the potential for democracy is substantially diminished,” Musk elaborated during the Code Conference in 2016.

Terraforming Mars: Adapting to life on Mars would be vastly different from what we know on Earth. Musk has pointed out that the initial Mars journey will be perilous, and those embarking on it should be “prepared to die.” He also envisions a strategy to heat up Mars: launching thermonuclear strikes to warm the planet and create a second sun-like effect over the poles.

Cautionary Advice on Semi-Autonomous Driving Technology: Musk has emphasized the importance of not discouraging the use of semi-autonomous vehicles, likening it to putting lives at risk. “And think carefully about this because if in writing some article that’s negative you effectively dissuade people from using autonomous vehicles, you’re killing people,” Musk cautioned in 2016.
