Our department had an unofficial policy of not teaching the latest tech and telling students that was something they can do on their own time.
That being said, with wireguard being merged into the kernel and it's huge significance to networking, I expect that tech to make it into the curriculum in some forum.
Learn about Wireguard. Nobody seems to be teaching it yet, curriculum always 3-5 years behind, and it's worth adopting into ed much sooner than that.
