So the solution he proposes at the end is to use Mantle? AMD has already proven themselves incompetent (or are they only unwilling?) at implementing OpenGL, unable to compete with either Intel or Nvidia, and now they want to fragment graphics APIs? And this is the 'solution'?

As for OpenGL's issues - that's what happens when a spec gets old enough. But the fact remains, it's the only graphics API that could be called 'universal', they have modernized the spec, and despite all its failings, somehow it still delivers better performance than DirectX...
