The question makes the assumption that "The World" is in any way coordinating or will ever coordinate to build AGI. I posit that "The World" has not and will not coordinate anything.
Are there global corporations and super power governments that are coordinating AI projects? Yes, but its not a singular AI project, The AI-sphere contains multitudes.
Also, AGI is a specific term and although its become more popular, its mostly a term Goertzel created because the term "AI" was being improperly used to label even simplistic statistical models like deep learning networks. At least that is how I saw it when I first read the term. I'm still looking for a free copy of AGI Revolution.
