Anil is an old-school technologist. He helped Movable Type which was arguably the first blogging CMS. He also worked at Fastly and Glitch. I'm sure he knows how CLIs work and what they're good for. And surely no one here is suggesting that for 99% of normie users that they'd be comfortable with CLI just because it's good at piping one command output to another. Even those of us who are proficient use GUIs more often.
