Don't get their point at all/.Scala was here a lot of time, but author still think that scala has "Great potential".

it looks like they're in a negation phase

whereas Kotlin fixes the immediate problem of Java being verbose

- well... there's a bit more to it than that. 🙂

What Scala primarily has going for it is Apache Spark. If that wasn't around I'm not sure Scala would be either. Sidenote: you can use Kotlin with Spark

That’s what happens when you create your build tool for your language because “you know better”

They have good libraries, Akka is really cool

@dh44t thats true. A lot of good ideas emerged from Scala, but also stuff that was a bit rich.

Being an official development language for Android has been a tremendous force multiplier for Java over the last 5+ years. Not that Java wouldn't be omnipresent without Android, but for younger and/or less prominent languages like Kotlin (and similarly, but probably a bit less so for Scala) that kind of megaphone makes a difference between being one of the top 3-5 languages in the world, and being somewhere at the 30+ position, where Scala is right now according to TIOBE (I know I know, that's far from an end-all be-all in terms of language value, case in point VB .NET).

May be not next month, because it needs a lot of blogs, articles, and materials around the web. For example, if you search “kotlin programming language” you get 340K results, and it was about 150K few weeks ago. Swift for example has 2.7M. Java like 10M. Long road ahead 🙂

Long road indeed, but you've started the engine and there's plenty of gas in the tank 🙂

i had the coursera lesson on scala years ago it changed the way i code java so i appreciate what scala brought to the table but the language is too rich (as @thomasnield wrote) it was designed by very smart people in lab coats while kotlin was designed by pragramatic professionals from day one having a keyword implicit is horrible for me my whole work is to replace implicit with explicit!
