Yes, you do. Multiple reasons, but first and foremost it is the easiest way to do anything on the internet that requires more than a few mouseclicks. Remember, most servers and computers, even your phone, is based on linux.

More reasons:

• Linux is free as in freedom and free as in beer.
• The mouse in linux desktops knows a nifty little trick: select text with the left mouse button and paste with a center button click. Seems obvious, but it works in all desktop systems, including the linux console, or command line interface.
• It's not bigtech, but development is done by bigtech people who need a decent operating system
• Linux needs few resources and can run on older hardware

Do you need to learn linux? Nope, as little as required, you will need to understand a few commands, but once the environment is set up, little maintenance is needed.
