It is my belief that the language, Aymara, of today is the Queshua spoken by the Aymara Natives at the time of the Inca Empire. I believe the Queshua of today is not the Queshua that was spoken then, but is a much evolved dialect of the original Queshua. One that the Aymara regard as impure and not worthy of them. Thus the Aymara call the original Queshua, "Aymara", to distinguish it from Queshua as it has become.

The article describes the Inca Empire as a theocracy organized along socialistic lines. That is true as far as it goes, but it would be better to call it a theocracy not only organized along socialistic lines, but also as a rigid cast system; with the priestly Incas on top, the warlike Aymara in the middle, and the conquered native tribes, who would become known as the Queshua people, at the bottom.

The article says about 45% of Peru's inhabitants are Native Americans, some of whom are descended from the Inca who established a great civilation in the region by the 15th century. That Inca would be Manco Capac, and he founded the civilization at the beginning of the 12th century. It would be hard for him to be the ancestor of any surviving Native American, because he was himself not a Native American,- as was pointed out by Garcilaso de la Vega. Note:  Spanish records show that by the end of the 16th century, all the Incas had been literally tortured to death for failure to embrace the Roman Catholic faith.
