The speaker is Clojure creator Rich Hickey, but the talk is about a mental model for thinking about complexity.

Inherent complexity involves tradeoffs.

Incidental complexity you can fix for free.

"And because we can only juggle so many balls, you have to make a decision. How many of those balls do you want to be incidental complexity and how many do you want to be problem complexity?"

The article is about the former. I bet the latter dominates day-to-day line-of-business coding.

Highly recommend the talk, as other have said.
