Every year I evaluate Scala for adoption. I'm a pragmatist, a polyglot, and usually never say no to seeing how things can improve my execution; which is why I chose to leave the door open for Scala.
And every year it doesn't make the cut for me (various reasons, probably well-known - complexity, compiler, tooling).
This is happening for the last, oh, 4-5 years now. Each year, I take away two weeks from my free time to try and force myself into it.
This year I made a special effort knowing that Spark and big companies adopted Scala. And it lucratively looks like data science is adopting Scala (or does it?).
Knowing LinkedIn is saying "enough" is a real breather for me. At this point, I can stop. Hopefully it will trigger a chain reaction, and leave Scala for the academics.
