Unfortunately for the vast majority of people, it absolutely is some kind of magic.
i've had to show people that they have to plug in their HDMI cable into their GPU instead of the motherboard, that they have to manually set the Hz in windows settings. how to install basic drivers.
so many more easy examples we IT-workers or nerds just take for granted. taking this to the extreme, my grandma asked me if i could search recipes online for her, because [insert your favorite search service] seemed too complicated.
So next to these examples, setting up syncthing with a VPN is next to impossible :( and even if they manage to set it up, good luck when you run into issues after a couple of months.
