If your code compiles in 1 second from scratch then what do you need incremental compilation for?
That's entirely fair. But, when I watch somebody like Jon Blow, with his 1 second from scratch compilation the result seems to be that he just iterates a lot more without being significantly more productive than I am. I can imagine for some parts of video game design fast iteration might be crucial, yet I struggle to imagine that compilation speed is what matters there. Systems design, art direction, plotting, these don't seem like factors where you need those one second compile times.
I really want incremental compilation in 100ms or less, this makes live reloading (such as with dioxus subsecond [0]) so much more enjoyable.
I don't care about the time spent on fully recompiling the whole project from scratch though.
