In my experience IntelliJ is a bad Scala IDE. While it has lots of cool advanced features, none of them make up for not being able to compile the basic language accurately: what good is an IDE where I can't 100% rely on getting a red underline for invalid code and no red underlines for valid code?

The parts where IntelliJ has always fallen down on Scala seem to be precisely the parts that are missing from Kotlin. I can't help feeling that the JetBrains team just "doesn't get" higher-kinded types at all. Which is a shame, because there is a lot of good stuff in Kotlin otherwise.

And naturally now they have a vested interest that Kotlin experience just feels better than Scala anyway.

It's improved in the last year or so. It's not perfect by any stretch of the imagination but I find that it's one of the better supported languages out there, second to of course Java/Kotlin/TypeScript/C#.

> Scala's tooling also pretty much sucks everywhere (interestingly the least sucking IDE for Scala is guess what ... Intellij!)

In your opinion.

Personally I almost get depressed when I have to switch from Emacs+Metals to Android Studio for Kotlin stuff.
