Responsibility is shared.

Google (and others) are (in my opinion) flirting with false advertising with how they advertise the capabilities of these "AI"s to mainstream audiences.

At the same time, the user is responsible for their device and what code and programs they choose to run on it, and any outcomes as a result of their actions are their responsibility.

Hopefully they've learned that you can't trust everything a big corporation tells you about their products.
