We are all eventually going to die...<p>It&#x27;s not about will Java adopt more Scala features, it is about how will it look when it is all glued together. I think for Java it can only go for worse, since language is massive as it is right now. Adding more would only bring more confusion for the table. Also good question is how will it work with other components of same language. I am not programming in Scala, I mostly read about it and read it. Still on faculty, but few older friends of mine, who have finished faculty 3 years ago and started to work at local startup&#x2F;small company all worked in Scala and they are amazed how good everything goes for the company and that couldn&#x27;t but notice that &quot;Developer Happiness&quot; factor being pretty high. So all those things considered tells you something...
