As a prominent researcher in AI safety (I discovered prompt injection) I should explain that Helen Toner is a big name in the AI safety community - she’s one of the top 20 most respected people in our community, like Rohin Shah.
The “who on earth” question is a good question about Tasha. But grouping Helen in with Tasha is just sexist. By analogy, Tasha is like Kimbal Musk, whereas Helen is like Tom Mueller.
Tasha seems unqualified but Helen is extremely qualified. Grouping them together is sexist and wrong.
That’s more the domain of “AI ethics” which I guess is cool but I personally think is much much much less important than AI safety.
AI safety is concerned with preventing human extinction due to (for example) AI causing accidental war or accidental escalation.
For example, making sure that AI won’t turn a heated conventional war into a nuclear war by being used for military intelligence analysis (writing summaries of the current status of a war) and then incorrectly saying that the other side is preparing for a nuclear first strike -- due to the AI being prone to hallucination, or to prompt injection or adversarial examples which can be injected by 3rd-party terrorists.
