Meet Matt King. He’s an engineer who works at Facebook HQ in California. He’s one of the people on a team who works towards making the big social network accessible. King explains the recent AI innovation on Facebook which describes photos to blind people. He talks about future aspirations and tells us what you can get to eat on Facebook campus, for free, at lunchtime. His favourite is a huge big salad, hence the title of this podcast.
