People dont' use Finder? "File system power users"? Are we talking about MacOS or iOS here? Seriously, I think that's an interesting take - that does not relate even a little bit to most work domains I ever was in contact with.
I think you might mean "Terminal". Console is an app that just gives you macOS's log spew. Also, I don't know any Mac power user, myself included, who doesn't use both the terminal and Finder. Most of them use iTerm2, actually.
