Well, sometimes I think the web is flooded with advertising an spam praising AI. For these companies, it makes perfect sense because billions of dollars has been spent at these companies and they are trying to cash in before the tides might turn.
But do you know what is puzzling (and you do have a point here)? Many posts that defend AI do not engage in logical argumentation but they argue beside the point, appeal to emotions or short-circuited argumentation that "new" always equals "better", or claiming that AI is useful for coding as long as the code is not complex (compare that to the objection that mathematics is simple as long it is not complex, which is a red herring and a laughable argument). So, many thanks for you pointing out the above points and giving in few words a bunch of examples which underline that one has to think carefully about this topic!
