Productivity, design and conciseness of Scala

I came across this survey

" What are the best (productivity-enhancing, well-designed, and concise, rather than just popular or time-tested) programming languages?"

and it suggests that some people find Scala less productivity-enhancing, worse design, and less concise than F#, C#, or python. What are your thoughts? Is scala productive and well design and should be higher on this list? Are Scala experts as productive as F# or C#? Will scala 3 be even better? Why people rated scala this way?
