No, it doesn't. Kotlin and Scala and other JVM languages use the JVM, they don't use Java. They can be compatible with Java and import Java libraries, but they don't need Java to work.
Yes and no, although it's possible in principe to have a 'Kotlin' KVM maintened by JetBrains. So far the JVM is closely tied to Java.
I have a hard time seeing what you could do in Kotlin without any Java interop. Concurrent collections, networking, most of the JVM ecosystem, it's all Java.
What do you mean? Kotlin compiles to Java Bytecode, it does not need Java libraries to work.
The JVM was developed for Java originally but has had features built in to facilitate developing other JVM languages.
About the ecosystem: MANY libraries and frameworks already have Kotlin versions, first in line Spring and Android. Kotlin has even been the preferred language for Android for years now.
Why would anyone think that?
Rust is way more suited to replace other systems languages, e.g. C and C++.
Java is more likely to be replaced by other JVM languages like Kotlin.
I had a lot of requests to make a blog on this topic
But Kotlin needs Java, so it can never really replace it.
No, it doesn't. Kotlin and Scala and other JVM languages use the JVM, they don't use Java. They can be compatible with Java and import Java libraries, but they don't need Java to work.
Yes, but without Java, there is no JVM. And especially Kotlin, you really need Java libraries for some things..
That's absolutely not true, the JVM is separate from Java.
And which Java libraries do you really need in Kotlin?

Yes this is true too
