Fast 5 Lightning Round:

1. What is your favorite book or book you’ve gifted the most?
   The Digital Doctor by Robert Wachter; also Klara and the Sun by Kazuo Ishiguro – about an AI-based robot with hyper observation skills but no full fund of knowledge.
2. If you could instantly master any skill, what would it be?
   Networking (with people) more quickly.
3. Would you rather have Super strength, super speed, or the ability to read people’s minds?
   Reading minds – “an essential skill if you’re a leader.”
4. What is something in healthcare you believe that others might find insane?
   That the sacred one-on-one doctor-patient model isn’t always best and that sometimes many-to-one or one-to-many clinics could be better.
5. What is the last movie or TV show you saw?
   K-Pop Demon Hunter; also recommends the documentary AlphaGo as a great illustration of AI.
