You should read again what I said. Do you think that simply using GUIs makes anyone less productive? You can’t think of any cases where a GUI is definitely better for a task than a terminal? If you think that , consider why the vast majority of people are using GUIs for everything, and only a tiny minority is using terminals for everything. It’s ridiculous, yes, to imagine you would be more productive if no GUIs existed (you just misunderstood my point).
