My Take - Although I agree with what the speaker is saying - this is only a part of the answer. This, and all else that impacts the Muslim world and keeps it from advancing is - they're Muslims. Islam breeds and nourishes the worst traits in humanity.
Winston Chruchill noted:
"Besides the fanatical frenzy, which is as dangerous as hydrophobia in a dog, there is this fearful fatalistic apathy. The effects are apparent in many countries. Improvident habits, slovenly systems of agriculture, sluggish methods of commerce, and insecurity of property exist wherever the followers of the Prophet rule or live. A degraded sensualism deprives this life of its grace and refinement; the next of its dignity and sanctity."
The Muslim world is a world of violent Medieval tribal societies with modern weapons, communications and transportation. No one trusts anyone else, and no one in their leadership ever wants anyone else to ever get an advantage because it may diminish them.
