IN FULL: Elon Musk’s Davos debut: AI, robots, Mars, and the energy bottleneck

From the World Economic Forum, here’s Elon Musk in a wide-ranging Q&A — his first appearance at Davos — in conversation with the chief executive of BlackRock. Musk argues there’s a single thread running through his companies: maximising the odds of a “great future” for civilisation — from making life multi-planetary, to using AI and robotics to drive abundance. He also flags the big constraint in the AI era: power — and points to solar and even space-based infrastructure as possible answers.
