In my terminal everything is a string. All of my tools are run from the terminal ( cloud provider, provisioning software, etc. )

I can chain cli calls together to create powerful workflows.

I have highly scriptable workspace management with tmux + vim.

I don't have to wait for web pages to load to run commands, I can just do the thing in the same place I do everything else.

Many people don't gain that much from the terminal but if you are a power user it makes your life great.

I don't like GUIs, they take too much space, are always trying to sell me something, present information in an inferior way ( I like my dark, cool colored termina l color palette ), and I can't script repetitive tasks.

most cli tools have the same conventions so learning new tools has way less overhead.

Just a few reasons.
