My read on this is not that he is claiming those things, but that he is examining those claims to see if they are true.
To be honest, not getting another breathless reiteration of the Functional Programming Dogma is a breath of fresh air. I actually like FP in the general sense, think interesting things are happening there, and am keeping an eye on it (as well as using it in selected places in my job where it makes sense, so I've actually put some cash down on the thing), but I'm really tired of people who have just barely learned enough FP to implement something of, say, this exact level of complexity making wild boasts about how good it is. I suppose it's a specific case of the general problem of seeing someone argue something you agree with, but badly.
This particular "integer stack VM implementation" is so trivial that you can't make arguments based on it. Both the imperative and functional implementations are too tiny to make pronouncements.
