I guess it's not really any scarier than 80s-era wire wrap prototyping, at the end of the day. Still, my hat's off to him just because he had the guts to try it!
He should send it to an FCC/CE test lab as an April Fool's joke.
In the 80s, we used Veroboard for that sort of prototyping. They would still have high-frequency problems given the huge amounts of additional wiring required, but I managed to get a Z80 board running at 3.5MHz. (Diagnostic slave board to a Sinclair Spectrum, so a bit simpler than the (very nice) board in the article).
Wire-wrap is actually quite good for durability, although it lacks an inherent ground plane. On the one occasion I had to send 20MHZ signals across wire-wrap, I had to make little twisted-pair lines by wrapping a ground wire around every signal wire.
I think you may have just repeated yourself there.
