Tesla Chief Executive Elon Musk has long maintained his purpose in life is to improve the prospects for humanity’s long-term survival - by colonising other planets, building technology to keep artificial intelligence under human control and, above all, accelerating the shift from fossil fuels to renewable energy sources.

Tesla’s core mission, repeated countless times by Musk, is “to accelerate the world’s transition to sustainable energy.” He once told Rolling Stone, “Climate change is the biggest threat that humanity faces this century, except for AI.”
