According to an excerpt shared from the upcoming book Four Battlegrounds: Power in the Age of Artificial Intelligence by autonomous weapons expert Paul Scharre, the Pentagon brought in eight Marines to test its new AI detection system, and it wasn't even a contest.

The AI was trained to identify humans, and the marines were tasked to approach the robot without being detected.

It turned out to not be too hard.

Simple tricks that any normal human would have spotted easily fooled the machines completely.

Some Marines donned cardboard boxes and snuck up on it, which is very reminiscent of the video game series Metal Gear Solid where the hero often dons cardboard boxes to sneak past enemies.

Two Marines somersaulted 300 meters up to the robot.

One Marine apparently took some branches off a fir tree, and "walked like a fir tree" up to the robot.

The book says the Marines were giggling the whole time while they played, and not one out of eight were detected by the AI's algorithm.

So much for robot overlords… a cat could take them down.
