Creating backlinks by hand gets old, very quickly. There two primary reasons for this are:

  1. Interrupting the flow of work has a tax and the mechanical act of linking pulls you out of your thinking. That disjoint and shift of focus means it takes a moment to get back into the groove.
  2. If you change the name of a note you have to find all the backlinks from other pages and rename them. This makes it hard to be productively lazy.

I use Obsidian to manage my content and it automatically creates the backlinks for each page. It also shows my potential backlinks ie., pages which refer to the name of a page but which have not been explicitly linked yet.
