Aliases are great - they can really save a lot of time, but I always caution people from using them too much. If you ever end up in a spot where you don't have any of your aliases, you'll be struggling to remember the original command.
This is a good point. You can commit your aliases to a Github gist, or other online source control, just in case.
Good point. I usually have all my settings in a Github repo where I can pull it down if needed.
