This is a very important point. Islam was a syncretist cult basically developed (in bits and pieces) to smooth the acceptance of domination by Mohammed's tribe. While the 12th century may have been decisive in solidifying and affirming Islam's anti-rational nature, it never had a solid basis that could be reasonably defended in the first place, nor did it have a reasonable way of looking at the world.
And by discarding reason it never has been able to look at the world except from the desert tribal view. While the world passed them by in achievement and knowledge, Islam never moved forward.
In any case, Islam has the ability to appropriate western technology for its own purposes. The Arabs sucked the life out of the Greco-Roman and Persian cultures to create a new sort of civilization. The Turks managed to do the same in the 14th-6th century, after which their “orientalism” led to their decay. Even now, they use western technology without contributing much to the sciences that made the new technology possible. I do think that their refusal to accept “secondary causes” is their problem. Ours. on the other hand, is to try to reduce everything to such causes.
