On the other hand, if you can do this and your co-workers can't, you may be tempted to write complex and entangled code, because the implications of each line are perfectly obvious to you.
Or you end up with something like Git, which is easy to use if you have the exact same background/education/philosophy as the person who wrote it, but has terrible usability for pretty much everybody else.
I don't have the same background as the "person that wrote it," and I consistently find the git command-line tools easier to work with than other tools (SourceTree, magit-mode, vim-fugitive, etc [1]). I think that in this case, it's just the mental model of a DAG[2] of commits that people have trouble wrapping their minds around. The tools are just there to help you slice and dice the DAG.
[1] I haven't used TortoiseGit, but I do imagine that having file browser menu items for files that are maintained by git could be useful from time-to-time, but I would still be using the cli most of the time.
To be fair, some of the usability complaints aren't about the interface so much as things like:
* Unreasonable ideas about the idea that commits/history can be rewritten, so therefore "nothing is safe."
* Arguments over how some git commands are similarly named to svn commands, yet don't do the same thing. The svn way is the 'right' way, and git is 'doing it wrong,' but really it's just an argument about familiarity (sharing many traits with arguments over Mac vs. Windows keyboard shortcuts, for example).
* Complaining about a recoverable error because they don't know about the reflog.
* etc.
I'm sure there are legitimate complaints, but most of the complaints that I see are around things like that.
If you invest the time into acquiring a faster and larger mental cache, you are unlikely to handicap your hard-earned capability with complex code. In fact, the new visibility can increase simplification and reuse.
The same restraint doesn't apply to someone naturally gifted with an exceptional memory, since they never went through the acculturation phase :)
