It depends on the problem. For some problems where you’re spending time mostly thinking, and relatively little time actually typing code, the compile times don’t really matter that much. For LLVM for example, with clangd configured to do code completion and syntax checking in the editor, you don’t really have to do as many build/test cycles. That said, I think fast compile times are important for the other use cases.
