Mazin Gilbert has an ambitious goal. As vice president of advanced technologies at AT&T, Gilbert wants to make AI technologies widely available throughout the corporation, especially to those who might not have a computer science background and may not even know how to program. Call it the “democratization of AI.” To accomplish that goal, AT&T is building a user-friendly platform with point-and-click tools that will enable employees — up to one-quarter of the company’s workforce — to build their own AI applications.
