Someone who knows what information to expect doesn't even need a label. Once you're past that hurdle, it's redundant.

For instance, you look at the dash of your car every time you drive, and what little is labeled is abbreviated. The expectation is that when you understand how the vehicle operates, the gauges and lights will make sense. The information is encoded behind your knowledge. dig isn't really different.

Some people want the tools to teach them everything, but that's just not appropriate or necessary, whether you're talking about a hammer, a firearm, or a computer.

KPH/MPH are ubiquitous standard abbreviations that exactly zero percent of people encounter for the first time when they drive for the first time. Occasional and brand new drivers will never not know what those things mean. Kilometers Per Hour is also 600% larger than KPH, and visual clutter while driving at highway speeds is a much bigger problem than when examining DNS records.

Yeah, then multiply that hurdle times the thousand others someone has to memorize to work in *nix.

Textual output on a computer is a communication medium-- hammers and firearms are not.
