C++ and Java, say, are presumably growing faster than plain C, but I bet C will still be around.
Sitting in my favorite coffeehouse with a new notebook and a hot cup of java is my idea of Heaven.
However, when Java is promoted as the sole programming language, its flaws and limitations become serious.
I was interested in Java the beginning, but the problem with Java is you do have to switch your platform.
I've never worked with the Java community.
Now, it's my belief that Python is a lot easier than to teach to students programming and teach them C or C++ or Java at the same time because all the details of the languages are so much harder. Other scripting languages really don't work very well there either.
When you write a program for Android, you use the Oracle Java tools for everything, and at the very end, you push a button and say, 'Convert this to Android format.'
This evolution may compromise Java's claim of being simpler than C++, but my guess is that the effort will make Java a better language than it is today.
No one wants one language. There are applications when it's appropriate to write something in C rather than in Java. If you want to write something where performance is much more important than extensibility, then you might want to choose C rather than Java.
In the Java Sea in Indonesia, I have seen fishers going out in the morning, six of them going out and coming back with five pounds of fish. That is the end point, a pound of fish per person per day to sell for rice. That's where fisheries go if you let it happen. That's where it stabilizes. These people cannot feed their families.
