Discursive Podcast
by Tim O’Brien
Each episode of Discursive takes one idea — from open source to FinOps, from AI agents to cloud cost models — and unpacks it through the lens of decades spent building the web, scaling infrastructure, and writing about how technology actually evolves. Recorded in Seattle, Discursive is a ten-minute conversation about where software has been and where it’s heading — across cloud, FinOps, open source, AI, and the culture that connects them.
