That’s fair. There are some available in other markets but they’re definitely fewer and further between.

Some phones do have built in radio receivers. If that’s genuinely a feature you want, they’re available.

There may not be proof that LLMs aren’t sentient, but there is some evidence and reason to believe that consciousness is an emergent property of quantum effects, whereas turing machines are relegated to classical mechanics. The same evidence would indicate it is unlikely that a turing machine could replicate the human brain since it uses fundamentally different layers of reality to calculate/think.
