I didn't watch the video but... Why TF did he choose Pop! OS with Cosmic Desktop‽ That's not something a non-technical user would choose. That's like... Beta software (Cosmic) running on a Linux distro made and tested for very specific hardware sold by System76.
That's like trying to put wheels made for a truck on a random sedan. Like, yeah you can do that with a bit of effort but why? It makes no sense.
If you're going to put a Linux distro on random hardware pick something universal and stable that was made to run on random hardware like Kubuntu/Ubuntu. Especially if you're new to Linux.
Also, if you're going to do something ridiculous like this why not just start with Gentoo? Don't use the GUI installer either! Go the LFS+ route and take care picking your file systems and compile flags 😁
BTW: Out of all the random people I've ever known to "try Linux", the ones who had the best first-time experience all used KDE (Plasma) as their desktop. That means Kubuntu, Bazzite, or SteamOS. For newbies, always go with KDE. Seriously: Its interface for settings and the launcher are familiar enough to both Windows and Mac users that they don't have a hard time while also being different enough that they don't make bad assumptions about how things work (which is a problem for Gnome).
Ah but we'll never run out of electricity. We will run out of oil.
Furthermore, adding new electric capacity is easy in comparison to adding more oil infrastructure.
