I mean, if you're concerned about the keystrokes, learn your editing shortcuts. Jumping to the beginning of the line is typically one or two keystrokes. But the parent obviously wasn't talking about the behavior of avoiding useless cats making you better, but the understanding that drives the recognition of which cats are useless and why you might want to avoid them. I'm... not sure about that claim, fwiw. On the one hand, I see a lot of people really mushy on the unix process model, what pipes are, how redirection works, etc. Firming that up is important, will lead you to be a better sysadmin and a better programmer if you work in a sufficiently unixy environment (and possibly otherwise), and spotting useless cats falls out of it. On the other hand, caring about useless cats is not a necessary consequence. Caring might motivate understanding... but might just lead to overfitting a bunch of poorly understood patterns to avoid the label. So I am skeptical. But you should respond to the claim actually made.
