In the original Chinese language, a "word" mostly consists of a single character. Interestingly, many of the compound words commonly seen in modern Chinese were in fact coined by the Japanese scholars during their attempts to translate western writings around the 19th century and were later "imported" back into Chinese language. Interestingly, the two examples in the article, "art" (美术) and "science" (科学) are both of Japanese origin, though one can still tell whoever coined the terms chose the individual characters due to their meaning being relevant to the concepts the words are describing.

If they already know the answer then it’s probably more efficient if they write it themselves rather than having AI produce a potentially difficult to verify answer and try to verify it.

If you can tell if a solution is correct or not --- well, then you don't need to have AI write it for you.

I think AI programming can only work when the industry begin to treat "almost working" systems backed by human customer service as acceptable.

I feel this is only the case because the ecosystem keeps receiving useful/low-entropy energy inputs from the Sun.

I'd say a better expression would be "we don't know yet whether ...", e.g.: "we don't know yet whether Covid is airborne".

I am not sure about that. If someone claims that you had stole something from a store, which you know you didn't, responding with something like "where is your evidence/you have no evidence" sounds perfectly reasonable to me.
