In this eye-opening documentary, actor Robert Downey Jr. explores the ways in which researchers are building A.I. tools that can enhance human physical capabilities, making us stronger, better, and more powerful.

How can A.I., machine learning, and artificial neural networks build an enhanced human body? What would the ethical implications of body augmentation be?

Robert Downey Jr., tech enthusiast and prominent actor famous for his role as Iron Man, set out on a journey to find answers to these fundamental questions.

Episode two of eight-part series The Age of A.I. focuses on three artificial intelligence applications that could revolutionize society as we know it.

From bionic limbs that behave naturally and understand the intent of the user, to vision enhancement that can save lives, or machine learning that improves racecar performance, this documentary explores the frontiers of what human bodies can achieve.

We have to stop viewing A.I. as something foreign and abstract – A.I. is here, and it's here to stay.

After all, human enhancement and augmentation have been around since the dawn of time, with the invention of the first primitive tools.

The only difference now is that we are breaking the limits of what scientists thought possible – across all dimensions of what it means to be human.

Today, we have the nearly unlimited computational power of machines, which promises to advance humanity to the next level.
