This is a much more meaningful litmus test for extreme capability. Building something like a 3D engine requires incredible mastery across multiple domains. The hardest part of these innovations isn't the software. It's developing an abstract mental model for the problem - repeatedly until it fits into an actual computer. When I work on my most extreme projects, I find the hardest stuff happens while I'm sitting around the house or scribbling on the whiteboard. Anyone who uses lines or hours of code as some statistic for capability can be instantly flagged as charlatan in my book. React is another good example. Absolutely nothing about it is a super deep pool of incredible innovation. The reason it's a thing is because someone had a very coherent vision in their mind for what the developer experience would be like. Then, they whacked at the workpiece until it approximated that idea. 10x is more about idea management than raw output.
