Well, I think Scala is a nice niche language but with a lot of problems. I like it but the tooling sucks and it is slow to compile. Compared to other ecosystems like Java or Kotlin there are still things to be improved if this resurrection is to take place. We'll see.

I’ve worked in mainstream companies e.g. Morgan Stanley who have made massive investments in Scala. The company I work at now ($5bn valuation) is 100% Scala.

It’s not a common language like Java, but I don’t mind that. It attracts smart developers who value the benefits of Scala over Java.

The Scala ecosystem has great libraries and platforms. It also gets the benefit of the entire Java ecosystem and the battle-hardened JVM.

The Java ecosystem is hardly a benefit

I worked at a Scala shop briefly back in 2010-2011. Slow compiles and bad tooling did not begin to describe it. I had hoped things would be better now, but I haven't touched it since.

Things are 100% better. It compiles in speeds comparable to my golang shop now.

Just upgraded to the latest 2.x compiler and it’s definitely leagues slower to compile than javac.

Scala is way different now and tooling is honestly great, unless you compare it with Java tooling (which is best in class).

Compile times got better but are still slower and can be quite annoying. Hope it will be improved further.
