Jeff Bezos is definitely a science fiction fan.

Working that Tony Stark brand, Amazon's billionaire founder strutted down a path alongside a robot dog at the company's MARS conference on Monday at the Parker Hotel in Palm Springs, California. The invite-only gathering of robotics companies and academics, first held in 2016, focuses on machine learning, automation, robotics and space exploration.

Bezos, a rare tweeter, posted the picture on his Twitter account to his 480,000 followers.
