If you are doing stuff in Linux that requires the terminal, you were probably making edits to the registry in Windows or pasting in wild powershell lines from online guides.

No need for 98% of the user base to ever touch the terminal. Open whatever software store comes with your distro, click install next to whatever you want.

The only exception to that is that sometimes, when a trusted person is supporting you through something, giving them a line to paste into a terminal might be quicker than walking them through all the clicks of a gui. Sometimes.
