But now it's too long for a power user. I would say terminal should be focused for power users and your average user shouldn't have to touch it in the first place if things just works. All they do is just use their browser and a couple apps, most users don't even know what power shell is in windows.

Just to make it clear, I don't mind terminal myself. I use nixos on unstable branch myself but it will never be mass adopted with this attitude (not yours but the original comment).
