Carl Sagan once said the following:
If you are skeptical, then no new ideas will make it through to you. You will never learn anything new. You become a crotchety old person convinced that nonsense is ruling the world.

If you are too much in the habit of being skeptical about everything, you are going to miss or resent it, and … you will be standing in the way of understanding and progress.

Usually, we do not think of adding tools to do something that our favorite already does—this would be like adding a redundant weapon. However, these alternate tools turn out to be great. PowerShell, to me, was one such tool.

- A Linux administrator, open to other scripting frameworks
- A system administrator who manages Linux as well as Windows workloads, looking to unify management
- A Linux administrator who wants a framework that handles—and aces in—structured data (as a side note, PowerShell is probably the only framework in Linux that works well with structured data)
- A Windows Administrator, new to PowerShell, wanting to learn PowerShell scripting
- A generally curious system administrator
