It doesn't fragment the community as you can call kotlin code from java and vice versa. Seamlessly. Kotlin is great in that it brings Java 8 features to Java 6(lambda expressions, functional programming, etc.) and more. It's a boon to productivity and makes programming in the Java ecosystem fun again. There is a sometimes increase in compiling speed but it's very marginal and the method counts increase with the transpiling but it's not noticable until the app get's on the larger side.
