Sure the more features that interact with each other the more the graph looks convex. But I strongly disagree with this:
"Project after project has demonstrated there is nothing about language or underlying technical infrastructure that changes that fundamental curve."
So we should all code in machine code? Perhaps what this shows is that all languages are very similar. Haskell, clojure, java, C#, C++, Rust, C etc they all are statement or expression oriented and data structure oriented. So, until I see languages that explore the rules/constraints and relations(similar to "out of the pit tar") I will remain unconvinced of this "all languages are the same" because assembly certainly isn't the same as java.
