I write Go and a bit Rust. I don't think compile time could be a huge problem, because: 1. There are ways to reduce it. For example incremental compiling, only recompile what's needed. 2. Many programmers already using CI when they're test/deploy/release their projects. And CI itself takes a long time to initialize and execute, basically throws away almost all the benefits of a fast compiler. 3. Let's don't forget the compiler could have different compile mode (Debug/Release mode), if Go wants to introduce it of course.
