Which programming language would have wide scope in future Java or .NET?

This isn't an either or question.  They are both orders of magnitude more in demand and used than any other languages out there.  I like to tell people they are the COBOL of our time.  Anything the enterprise embraces like this has decades of life.

In future maybe no one will use Java or .Net In past we had Cobol, Basic, Fortran, Algol, Pascal and languages like A, B, …. Z Now we hear less of them. Its not like they aren't good anymore. But languages and scripting languages which provide better performance, better memory management, lesser lines of code, reusable, less development time, less time and space complexity and with lots of other developer friendly features has arrived. So as a programmer we should be ready for change based on the changes tat arise in the science of computing. Now languages like Python, Perl, Ruby, Scala, JavaScript are being used for client side programming. New languages like Dart from Google are coming which promise lots of good features in web development. Java and .net will be used in future also since lots of companies had built there software infrastructure on them and we will have to support them for next few decades by the time we figure out to build systems without using languages.

Just comparing Java and .NET, my bet would be on Java for sure.  I was talking to some people in Google and they mentioned that they are either scrapping off or porting their .NET projects to Java.  So, my bet would be certainly on Java, between the two. Not only with Google, its true with most of the major companies.  Apart from Microsoft of course!
