I agree. Although for most tasks I tend to prefer having a command line interface, just because of things like programmability and my typing speed, I'd be lying to go as far as to say the CLI is _always_ the best way to do something. For example, I like to construct git commits using a GUI, since I'm faster at selecting lines to commit than I am sifting through potentially hundreds of changes looking for the right one to add to a particular commit.

Additionally, I think some of the listed tasks are objectively better in the GUI, despite being possibly slower. For example, in the command line, deleting a file doesn't send it to the "Recycle Bin" or your OS's equivalent, it simply deletes it. This is better for things like scripts, but worse for someone using it as a GUI replacement, since now there's a risk that they could permanently delete an important file due to misspelling or something of the sort. I find it hard to remember sometimes that Emacs is a GUI too, and it can often be the best way to do any given task.
