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. Nearly 200 teams from around the world have spent more than a year in impoverished villages in Tanzania trying to achieve the global literacy challenge. The winner of this latest competition will be announced in Los Angeles Wednesday, May 15. (AP Photo/Jae C. Hong, File)
