we've seen so far, I'd sort of pick ChatGPT. You know, it wasn't the underlying model that mattered, it was the usability of it, both the RLHF and the interface to it. - What is ChatGPT? What is RLHF? Reinforcement Learning with Human Feedback, what is that little magic ingredient to the dish

Nice to see Sam getting interviewed by an actual AI.
I don’t follow Mr. Altman so it was really interesting getting to hear so much of him. He is mostly very careful, and even a bit tense in some moments, for such a relaxed interview. And that Alan Turing quote at the end was top notch, a testament of the brilliance of its author. Well done Lex!

Impressive program! For a brief moment of 15 seconds (your customary pause time 😊), I harbored doubts about your proficiency in your field. However, upon immersing myself in your show, I swiftly recognized your thoughtfulness, considerate nature, exceptional intellect, and impeccable manner in addressing various su...
Listening to this podcast made me realise two contrasting thoughts. Firstly that these two professionals are super intelligent and nuanced people. Secondly that with regards to AGI these great minds can only conceptualise thoughts within the limitations of their human experience and that they like the rest of us, wi...
