In this touching documentary, world-renowned actor Robert Downey Jr. explores the ways in which emerging A.I. technologies can revolutionize medicine, by helping people battling incurable diseases regain their lost abilities.

How can artificial intelligence, machine learning, and artificial neural networks create a new world in which all diseases will be curable, and personalized high-quality healthcare will be the norm, not the exception?

Episode two of eight-part series The Age of A.I. sets out to examine the fragility of the human body, and how scientists can find a way to address and correct its limitations.

Narrated by Robert Downey Jr., science enthusiast and prominent actor, this documentary introduces the cutting-edge technologies that might revolutionize medicine – perhaps going so far as to eliminate the need for a healthcare system altogether.

The episode follows the heart-rending story of athlete Tim Shaw.

In 2013, the former NFL superstar was diagnosed with amyotrophic lateral sclerosis – otherwise known as ALS.

ALS is a rare neurological disease that often gets progressively worse over time. In Shaw's case, it led to the end of his athletic career, and eventually the loss of his ability to speak and walk.

Despite all this hardship, Shaw has been able to regain a sense of normalcy with the help of A.I.

Between speech recognition or synthesis, communication applications, and image analysis, Downey explores a series of groundbreaking developments at the frontier between medicine and A.I. technology.
