Can someone please explain to me like I'm a 5yo; Why, if at all, this is significant? It "seems" significant, but no real idea, TBH.

NOTE: I just skimmed very quickly the article and the linked article referring JTAG.

I believe it is providing tools which allow running the Intel CPU in a way equivalent to running a regular program on GDB. It may be possible to use a JTAG but not sure if it is a requirement.
