Medical ethics is a serious subject, and then there was Asilomar on the ethics of genetic engineering. Just because this AI ethicist isn't one, it doesn't follow the field is worthless.
The Asilomar Conference on Recombinant DNA was a high-caliber event. The paper here, done at Google, a leading AI company isn't, and the ethics-washing on view here is deeply concerning.
That’s the crux of the problem. Top tier academia and ethics both attract the absolute best and the absolute worst. So I suppose we need both the critical cynicism and the optimists in threads like these.
