>the existing infrastructure and computing devices all rely on register based machines, and run imperative instructions I don't think the author is disputing this at all, but positing that for writing application layer programs this is unnecessary complexity and ought to be abstracted by the language/compiler. Perhaps as it stands our programming languages are too general purpose; in future, will we see a clearer distinction between languages for different purposes?
