You touched just the surface as there are many more reasons why languages change drastically over time, ChatGPT being a rather mild one. Mass migration is another one, especially in Europe this is dramatic, when e.g. in German schools 80% or more of the children are not talking German at home. The woke gender agenda is another one where in some languages with grammatical sexes so-called scientists and experts systematically mutilate languages by enforcing the genderism on grammatical sexes where it does not belong in order to fight against discrimination. English is an exception as it has no sexes on words, but the German language is hit hard by this.
