Ryan Williams (@rrwilliams), MIT professor and Gödel Prize winner, is interviewed…

Brief

Ryan Williams (@rrwilliams) appears in a 2026-06-29 podcast interview where he solves a LeetCode 3SUM variant faster than the canonical 'optimal' method and outlines research in fine-grained complexity, SAT solving, and a proposed strengthening of P vs NP. The episode also covers simulating space with time, career advice, book recommendations, and links to video, audio, and a transcript.

Why it matters

Ryan Williams (@rrwilliams), MIT professor and Gödel Prize winner, is interviewed in a podcast episode posted 2026-06-29 where he answers a LeetCode 3SUM question and presents a solution claimed to be faster than the popular 'optimal' approach (00:41 and 03:54).

Key details

  • The episode covers technical topics with timestamps: fine-grained complexity (08:26), a 'severe strengthening' of P vs NP (17:00), SAT problems and solvers (24:38), hot takes on famous open questions (34:51), and simulating space with time (46:57).
  • Practical and career segments include why he solves hard problems (01:01:02), how to pick good research directions (01:02:35), and technical book recommendations (01:07:14); available on YouTube (piped.video/AaK1SL2i_4Y), Spotify, Apple Podcasts, and a transcript (developing.dev/p/mit-complex…).
Source evidence

Ryan Williams (@rrwilliams) is a professor at MIT and the winner of the Gödel Prize in theoretical computer science. I interviewed him all about his work starting by asking him a popular Leetcode question (3 SUM).
