Billionaire Elon Musk said Wednesday that he anticipates finding a CEO for Twitter “probably toward the end of this year.”

Speaking via a video call to the World Government Summit in Dubai, Musk said making sure the platform can function remained the most important thing for him.

Musk, 51, made his wealth initially on the finance website PayPal, then created the spacecraft company SpaceX and invested in the electric car company Tesla. In recent months, however, more attention has been focused on the chaos surrounding his $44 billion purchase of the microblogging site Twitter.

Meanwhile, the Ukrainian military’s use of Musk’s satellite internet service Starlink as it defends itself against Russia’s ongoing invasion has put Musk off and on at the center of the war.

Musk offered a wide-ranging 35-minute discussion that touched on the billionaire’s fears about artificial intelligence, the collapse of civilization and the possibility of space aliens. But questions about Twitter kept coming back up as Musk described both Tesla and SpaceX as able to function without his direct, day-to-day involvement.
