The 20th chairman of the Joint Chiefs of Staff believes growing artificial intelligence and unmanned technology could lead to robotic military forces in the future.

“Ten to fifteen years from now, my guess is a third, maybe 25% to a third of the U.S. military will be robotic,” said retired Army Gen. Mark Milley at an Axios event Thursday launching the publication’s Future of Defense newsletter.

He noted these robots could be commanded and controlled by AI systems.

Advancements in technology and changes in the nature of war will enable militaries worldwide to make smarter and faster decisions, Milley said.
