When you're communicating with a person, sure. But the point is this isn't communicating with a person or other sentient being; it's a computer, which I guarantee is not offended by terseness and lack of capitalization.

> It's akin to shopping carts in parking lots.

No, not returning the shopping cart has a real consequence that negatively impacts a human being who has to do that task for you, same with littering etc. There is no consequence to using terse, non-punctuated, lowercase-only text when using an LLM.

To put it another way: do you feel it's disrespectful to type "cat *.log | grep 'foo'" instead of "Dearest computer, would you kindly look at the contents of the files with the .log extension in this directory and find all instances of the word 'foo', please?"

(Computer's most likely thoughts: "Doesn't this idiot meatbag know cat is redundant and you can just use grep for this?")*
