These days I can say the same, I used to enjoy trying to minimize my mouse usage and fiddling with tiling window managers but now I just can't be bothered.
And the weird thing is that the type of mental effort required is not even a useful one per se, it's more like a strain (to me) than something that makes me sharper.
Still some things are easier in a GUI while others in a CLI, just depends on their nature and how often do you have to engage with them. But after a while navigating windows by Alt+Tab (Alt+`) or the mouse is fine really. I don't care to reach for Super+PgDown/PgUp when I can move my mouse to the corner of the screen and scroll to change the workspace.
That’s a good way of putting it. CLI skills are specialized skills that I’m not going to use for anything else, whereas using a desktop environment is re-using skills I already have for other purposes.
Even when I do write code, I spend more time thinking about the code than actually writing so losing time to using my mouse doesn’t matter.
