Look, I've been using Scala professionally for 8 years. I don't notice that my compile times are any slower than Java, although I haven't tried any meaningful comparison. There are some notorious libraries like Shapeless than can kill your compile times; the solution is to not do that, unless the trade off is worth it to you. It could be x1.2 slower, maybe even 2x, and I wouldn't notice it, because it is fast enough. IntelliJ has incremental compilation. Compile times only matter when I do a full rebuild, and it is still fast enough. If I had to build a giant mono-repo like at Google, then the compile speed of languages like Go become important.
