This is a me thing and not related to this video specifically, but I absolutely hate that we've settled on "homelab" as a term for "I have software in some computer I expose to my home network".
It makes sense if you are also a system administrator of an online service and you're testing stuff before you deploy it, but a home server isn't a "lab" for anything, it's the final server you're using and don't plan to do anything else with. Your kitchen isn't a "test kitchen" just because you're serving food to your family.
Sorry, pet peeve over. The video is actually ok.
