Is it declining? Citation needed? I agree that Scala is not the new kid on the block anymore but I don't see it decline. When you look at the language rankings of the last few years, Scala seems to have settled at about ~12th place currently.

Depends on the criteria and the group of companies you survey. In our customer survey done mostly among top 100 enterprises it comes at #3 very close to Python (which is #2), and it is much stronger in absolute numbers than C# or JS. And the trend is growing.

Of course, this is not representative to the whole market and heavily biased towards big companies with big backends that need to scale, but neither are Tiobe, GitHub or SO rankings.
