I wouldn't build killing tools casually despite having, as most engineers here do, the ability to do it in a wide variety of manners that would be innovative from a technological standpoint. It's presented as art and I criticize it as such, there is seemingly no strong intent at least none presented in the post, and the form is not particularly appealing or interesting. It's explosive charges strapped to a helmet with a detonator. The concept itself is not novel, as you said it's been done a hundred times in a million animes.

I don't know Palmer beyond this blog post and having googled him after being baffled by the tone. I don't dislike him and I don't know his politics.

I would have loved to have heard one of the many beautiful stories he mentioned, and I was particularly confused by seeing the lovely wedding photos at the end. It made me question whether it was satire but I don't think it is.
