In that third criticism I'm talking about more than a mere philosophical ideal. I'm talking about the trajectory of human history, especially about the history of technological advances. See, for example, Moore's law and the Kardashev scale.
As for the incoherence, sure once we became gods with perfected technoscience we might be free of incoherence in our worldview if we dropped atheism at that point. My point is that we're atheists now, today, while we're actively trying now, today to become gods in the distant future. You don't think there's anything fishy about that?
