I've always admired the clarity of thought of Rich Hickey [1], creator of Clojure. I wish I could point to a single article or post that outlines his philosophy, but they're all over the Internet. I used to spend hours in the early 2010s scouring the web for his writings/videos.
What I find admirable about Rich is that he was originally trained as a musician, yet has an impressive theoretical grasp of software concepts and is tempered in his designs by way of a battle-tested pragmatism (stemming from his having written software for real-world systems).
I've never written a single line of Clojure (and it's unlikely I will ever do so), but his thinking process has been an inspiration to me.
