'AI for good': Is AI the solution to humanity's biggest challenges?

This week, Tech 24 takes a look at so-called "AI for good", or how artificial intelligence can be used to help solve society's biggest challenges. We speak to Estevam Hruschka, a professor of Artificial Intelligence at Carnegie Mellon University and a founding member of the AI for Good Foundation Steering Committee. Also, on Test 24, we try the Hyvibe guitar, an acoustic guitar that uses smart vibration technology to turn itself into a bluetooth speaker.
