These kind of write-ups all have an implicit premise that is unstated: they're talking about corporate AI run by corporations. They're not actually talking about the technology. Corporate AI will never be ethical or safe because corporate persons have different motivations and profit incentives driving them than human persons do. And most of the time they're quite nasty when viewed through the lens of human ethics.

It reminds me of the parable of the blind monks each feeling a different part of the elephant and arguing about it's shape. They're each not wrong, but they're also only talking about a limited subset of the elephant (AI).

Cory Doctorow is much more eloquent in his explaination of this important distinction in his reverse centaur metaphor.
