You can learn a lot on Youtube, I've done car repairs by watching a couple of youtube videos, There's a lot of non fukkery on Youtube, but the nikkas doing "current events" commentary and doing multihour livestreams talking shyt and begging for donations is where the focus is.
I built my first PC with Youtube
Fixed countless PC problems with Youtube
Learned the essence of Linux through Youtube
Despite Youtube being a cesspool of butt, I thank that platform with helping me get through my rough of techie years
