Build a Second Brain You Actually Own

In this AI marketing podcast episode, Dan Sanchez and Travis unpack why context is becoming the real moat in AI (not “killer prompts”), and how to future-proof your personal knowledge base as models leapfrog each other. They break down a practical “second brain” setup using Obsidian + code agents (Codex / Claude Code), cover a meaningful upgrade to ChatGPT Deep Research (choosing where it pulls sources from), and end with a reality-check conversation about AI disruption—plus a wild new video demo from ByteDance’s Seedance.
