Beyond the Hype: What Silicon Valley Gets Wrong About RAG. Amr Awadallah, founder & CEO of Vectara

We get into why RAG is far from dead, how context windows mislead more than they help, and what it really takes to separate reasoning from memory. Amr breaks down the case for retrieval with access control, the rise of hallucination detection models, and why DIY RAG stacks fall apart in production.

We also talk about the roots of RAG, Amr’s take on AGI timelines and what science fiction taught him about the future.

If you care about truth in AI, or you're building with (or around) LLMs, this one will reshape how you think about trustworthy systems.
