Apple's incompetence in AI / Assistant etc stuff has to be studied.
Now it just says something like "A message in a different language".
For example, Android and Google Assistant has had excellent support for Polish for more than a decade. Siri still doesn't support Polish at all, even though all of Apple's AI suppliers support Polish perfectly well...
Why should Apple focus on technical excellence when the company and their products are touted for literally gimmicks? In the end this is what brings the money and profits through the door, can't blame a company for providing what the market craves.
LLMs are eating software, maths, and LinkedIn posts; some of the image generators are seeing similar (limited) success.
Other than that, my general impression is that most people think of even the best as garbage.
("Other than". In fairness, most people thought LinkedIn posts were already garbage, it's just that it wasn't made any worse by LLMs).
They took like 7 years to come out with a foldable iPhone remember - lol!
