Is this a real opinion people have, or am I misunderstanding...
It sounds like you're recommending people to not understand the shell one-liners they're pasting into their CLI and instead just verify that the outcome was observed after the fact?
That's pretty much the opposite of what I've understood to be "good terminal practice" for my entire life, which can be summed up as "don't execute anything in the terminal that you don't understand".
Is "just paste it and hope you don't lost data/just installed a virus" the new modus-oprandi?
