I have recently read, and listended to podcast about the Inca. In all cases the quipu is talk about as definitively not a fully developed way of writing down the Inca language. In university (ca.10 years ago) we where hover thaught that the question was up for debate. So I wonder what has changed in the knowledge and understanding of the quipu in that time? What are the arguments for it being a fully developed way of writing the Inca language and what are the arguments against?
There have actually been a lot of exciting developments in the understanding of khipus as writing in the last 10 years! I wrote about it previously here but am happy to answer any follow-up questions too.
