Secondly, again, I'm sorry, but it's true.
The Aztecs didn't have either the wheel, or metal working that was even on the level the Ancient Egyptians could boast 4000 years ago. How on Earth were they supposed to have an "Industrial Revolution," or harness electricity with those handicaps?
Were they just going to warp through millennia worth of technological and socioeconomic development overnight? The very idea is ridiculous.
SubSaharan Africa couldn't even hold a respectable empire together for more than a few decades. That problem also wasn't going to correct itself any time soon.
I'm sorry, but you're preaching fantasy here.
