I appreciate the complexity and depth that these interviews go into. My favorites are the ones that ponder the origins of life, consciousness, and reality. Lex, thank you for your journey to understanding the human condition!

She’s igniting my desire to go back to school and learn science in a more formal way. I think about this stuff daily but I have very basic understandings and keep pausing the video to research terms you use, and concepts I am not familiar with. this woman is really hitting me in a personal place with her mind and how she thinks. I am mesmerized with the subject matter and her profound thoughts and understanding. I’m in awe of such intelligence really. And you too Lex, brilliant, you have such an amazing understanding of so many subjects and I love the summaries of your guests answers you give as a response they really aid my understanding of the content. You push my boundaries with your podcast and I think you ask the best questions.

I like that you ask the easy questions like why does anything exists 😂

I love her approach to the podcast, the way she lays out thoughts and how open she is, and how deep she’s willing to get into it. Love for Lex who’s so curious about many things and shares it with us in this way!

Sara is brilliant and I like how Lex just lets her speak and lay down her theories and findings! She's as much a philosopher as she is a physicist.

Yes, we all are waiting for the footages of ayahuasca, episode after another one.

This woman is absolutely perfect for what she is doing in her field. I love this third talk SO much!

I love the way she talks!! I love the way she thinks so deeply and complexly, but paints it so clearly with her words. It’s freakin beautiful!!😭😭
