1. She has 2 BAs, one in math and one in mechanical engineering.
2. She was an "Advanced Concepts Engineer at Zodiac Aerospace from 2012 to 2013".
3. She was a product manager at Tesla on the Model X
4. She was VP of product and engineering at Leap Motion.
Going from that fact that she wasn't a deep learning researcher to "her history was entirely non technical up until Open AI" is plain false. And plus, the job of CTO is 90%+ people management, and she appears more than smart enough and experienced enough to evaluate technical decisions of her team.
For the record, I doubt the CTO of OpenAI is the best person to fund if you're looking for trade secrets on training and deploying SOTA LLMs. They are two levels too far from reality to know anything useful.
