Musk is funding the 2019 XPRIZE for $10 million, which presented a challenge: Come up with open-sourced software that could easily be downloaded onto tablets used by illiterate children to teach themselves to read. But that’s what nearly 200 teams from around the world have spent more than a year in impoverished villages in Tanzania trying to do. The winner of this latest competition will be announced in Los Angeles Wednesday, May 15. (AP Photo/Jae C. Hong, File)
