Business coach Terry Kim has posted an extended thread highlighting the achievements of John Carmack. Kim explained how Carmack single-handedly and permanently changed the scope of both gaming and aerospace by coding the original id Tech engine for Doom over 28 hours, creating a modular approach to building games (and later rockets) that forever changed the two disparate industries.
As Kim spins it in the full thread, which includes some video excerpts from Carmack interviews throughout the years, "This is the power of true innovation: It's not just about solving the problem in front of you. It's about developing principles that can transform entire industries. [...] Greatness requires obsession. When Carmack coded for 28 hours straight, he wasn't just meeting a deadline. He was pushing the boundaries of what is possible."
