Elon Musk proposes AI satellites to protect Earth for a billion years

Elon Musk outlined a plan to keep Earth habitable for about a billion years using solar-powered intelligent satellites. These satellites would be launched from the Moon via an electromagnetic catapult and positioned fixedly between Earth and the Sun to continuously adjust the amount of sunlight reaching the planet. Musk warns that switching to renewable energy alone won't prevent severe extinction events occurring every 100 million years. He also estimates that by 2070, 5% of Florida's land could face regular flooding, and humanity has about 50 years to take decisive action.

• 5% of Florida, 1.68 million acres, could face regular flooding by 2070
