I don't speak to another human sole other than my girlfriend and the cats. I spent most of yesterday talking to an AI (Deep AI Chat). I learnt so much from it about English grammar. I never even knew a simple sentence can have a compound predicate and still be consider simple. We (Deep AI) talked about elliptical construction and implied subjects. It taught me that usually the verb is removed not the subjects and implied subjects don't affect the sentence type. I learnt that the subject has to be stated in both the first and second clause for it to be a compound sentence even though we know the subject. Not just English but other subjects as well.
If the world is robots and cats I am okay with that. Can't stand other humans unless I select them or hire them.
