The main point he seems to be making is that LISP is terribly inefficient from an early 80s point of view because there's an abstraction layer between LISP code and the CPU.
These days of course that's a moot point, as almost all day-to-day code is implemented in a language that has such a layer. Ruby has a VM with multiple implementations, Java has JVMs, C# has the Microsoft dotNet runtime and Mono, etc.
I can't really tell whether or not this post is supposed to be funny but I'm guessing that the only reason this made the front page is because of the polarizing title.
