Here are a few quotes from the episode:

“AI is a great accelerator if you already understand the fundamentals. If you don’t, it just magnifies the problem.” - Chris Reilly
“There’s a missing middle right now where people are skipping the fundamentals and jumping straight to the results.” - Chris Reilly

Chris emphasizes that while AI and automation can improve efficiency, they do not replace the need for strong accounting knowledge, modeling fundamentals, and business understanding. He explains that the best modelers focus less on tools and functions and more on clarity, reliability, and helping decision makers understand what to do next.
