Rana is co-host of the new PBS Nova Wonders series, and is featured in the episode entitled "Can we build a brain?" This episode explores how today’s A.I. actually works—is it truly intelligent? And for that matter, what is intelligence? The world’s brightest computer programmers are trying to build brighter machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power. NOVA Wonders looks at how far we’ve come and where machines are headed as their software becomes ever more…cerebral.
