I think the article is forgetting that the "tech industry" includes startups. Sure bic companies are rigid top tldown structures, they need to be to accomplish what they want to do. But those companies aren't the ones we look to to break new ground in technology. The market as a whole Is not hierarchical and those who participate in the corporate structures are free to leave AMD start their own structure. That's what makes California the 5th largest economy in the world and while the Soviet union is dead.
