One Dutch company controls 100% of the machines that make advanced AI chips. One Taiwanese company manufactures 71% of the world's semiconductors. And the materials for the next generation of chips - gallium from bauxite - sit largely in African soil. The question is whether Africa captures any of the value.

Africa generates the AI queries. Africa pays the bandwidth bills. But the servers doing the thinking sit in Amsterdam, Virginia, and Singapore. The Stack Sovereignty Test turns to its second pillar - Compute - and asks the question that determines everything else: who owns the machines that think for you?

Africa is producing more AI-capable graduates than ever. And losing more of that capacity than it can afford. The Stack Sovereignty Test reveals why talent isn't just one of five pillars - it's the variable that determines whether all the others can be built. The window is open. It will not stay that way.
