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.
She is extremely knowledgeable about the details of all the ways that AI can cause catastrophe and also she’s one of the few people with the ear of the top leaders in the DoD (similar to Eric Schmidt in this regard).
Basically, she’s one of a very small number of people who are credibly reducing the chances that AI could cause a war.
If you’d like to learn about or become part of the AI safety community, a good way to start is to check out Rohin Shah’s Alignment Newsletter. http://rohinshah.com/alignment-newsletter/
