> Admit that it would be the same.

Sorry, can't do that. If my estimate was 2 months in Scala, it would be 6 months in Java: 2 to write the software, and 4 to find and chase down all the NPEs, casting exceptions, and concurrency bugs, while building a test kit for things the scala compiler already verified the moment my scala code compiled.

Last time I've had casting problem was when someone passed Scala Map to Freemarker. If it takes 4 extra months to debug NPEs, then someone still needs to learn how to code, because things that compiler can fix, experienced programmer should be able to do avoid at first place.

That's what I hear. I personally think it's a shame that we have to live through years of terrible bugs in terrible languages just to become an experienced programmer that can finally know how to always avoid those mistakes in the first place.

If you're already there, great. I applaud your superior experience, and hope you really enjoy your C++ footguns. But don't tell me that the scala compiler doesn't have value to me just because you're a code god and don't need it. I actually benefit from languages that help me avoid stupid mistakes.
