It is always amazing when anyone takes something that has nothing to do with the issue, like who the Akkadians were, and generalizes it to the point where one should think that .....yes, that is right!!!!
The Akkadian language has nothing to do with who they were, and they clearly did not speak Arabic. And that language did not evolve into Arabic, either.
There are different people living in Arabia, as there were different people living in Mesopotamia, or in Ancient Canaan, and those people continue to be distinct from each other, regardless of the fact that so many of them have had their identity disappear with time.
Akkadians were not Arabs, and cannot be forced to be.
They were still Arabs from the Arabian peninsula... Who do you think they were?
