The article itself criticizes Jaynes' use of The Iliad as an example; he handwaved these criticisms away by saying that "consciousness" was added at a later date. The article is candidly critical of Jaynes and so are all the quoted scientists.
A lot of people here seem to think this article is promoting Jaynes' arguments or hypothesis but it's not. I'm not surprised though, most hacker news posts on controversial topics are usually advocating for or against an idea; the faster you can write off the argument as bunk the more time you save for other worthy content.
This article is a discussion of speculative science, not an argument. How does it contribute and how does it fail? What does it mean that we choose to speculate or apply the scientific method? It gives perspective on how we research questions now and the role of religions and myths in the past.
