I can give an anecdote if that's helpful. Imagine you're wanting to download an object from S3. You start to type out the command in your CLI. You hit enter, only to realize, see that the object is not found. You have a typo somewhere... but where? The bucket is huge so, you resort to listing the contents and passing the results through grep. Then you copy the object to the clipboard so that you can edit your original command.

I see one of the other comments mentions K9s. The exact same use cases manifest with that tool. YES, if it's just a one-shot, nothing beats the CLI. Many things where you need to investigate the resources a bit more, lend themselves to a TUI (or GUI if that's your thing).

I come from an era where folks could fly through tasks on dumb terminals. (AS/400 apps). The moment we gave them "better" gui tools, they slowed way down. No matter how many times we told them, "you can still use your TAB and ENTER keys!" TUIs were just a sweet spot.
