'Aliens and deep tunnels': Elon Musk offers vision for future at G20

Sitting in the dark, wearing a traditional Indonesian batik shirt and surrounded by candles, Elon Musk offered a vision for the future that includes aliens, deep tunnels and rocket tourism.

The Twitter owner appeared by video link on Monday to address business leaders in Bali on the sidelines of the G20 summit.

“We had a power outage three minutes before this call. That’s why I'm entirely in the dark,” he told Indonesian tycoon-cum-moderator Anindya Bakrie.

Musk was asked why he had not travelled to the tropical Indonesian island and the new Twitter boss joked that his “workload has recently increased quite a lot”
