In our past, this seems a community thing: Someone in your neighbourhood had advanced knowledge in welding, someone else advanced electricity, masonwork, clothes repair, ... They could coach other people to a basic enough level and help if unexpected troubles popped up. The community as a whole had knowledge and basic apprenticeships built in.

Today, repair is something you do on your own. Things like youtube are a great help, but the community aspect is lost.
